Sci-fi is the genre I keep returning to when everything else feels thin. Fantasy can be transportive, and crime shows can be addictive. But science fiction is the one that keeps picking at the scab, consistently asking the hardest questions about who we are, what we’re building, and what we’re becoming in the process. It’s wild how all of that is often disguised as a show about robots or time travel or a man with two hearts. I’ve been writing about this genre for half a decade now, and the longer I do it, the more convinced I am that the ceiling of sci-fi TV is higher than almost any other form of storytelling.
To make this list, a show has to leave a mark that outlasted its finale. Long after I’ve forgotten plot mechanics or season endings or who won what award, I’m still turning over the ideas and marveling at the formal, thematic, and emotional beats that stopped me cold. I rewatched significant portions of a couple of these sci-fi shows over the last eight months, some of them for the third or fourth time, and came away with a higher opinion than I’d started with.
Why You Should Trust Me: I’ve been covering science fiction across movies and TV shows for six years, the last three and a half at MovieWeb. In that time, I’ve written hundreds of lists across the genre, from deep dives into hard sci-fi to franchise coverage and recommendations. The shows on this list are the ones I adore, rewatch from time to time, and am willing to argue about at length.
Honorable Mentions
- Lost (2004 – 2010): I would be lying if I said the first three seasons aren’t among the finest sci-fi TV ever made. The mythology, the ensemble, and the structural invention of the flashback had me reeling the first time I watched. But then the writers admitted they didn’t know where the island was, and the final two seasons became a disappointment. So, this is a painful omission.
- Andor (2022–2024): The funniest thing Andor did was make the rest of Star Wars look lazy. Tony Gilroy took a supporting character from Rogue One and somehow created a politically mature series without Jedi or the Chosen Ones. However, it lost the tiebreaker to The Expanse on scope and to Battlestar Galactica on cultural impact.
- Silo (2023 – Present): Every few years, a show arrives that makes me irrationally excited about weekly releases. Silo did that. The premise is great, the execution is even better, and Rebecca Ferguson is exceptional. But two seasons aren’t enough to warrant a spot on this list. So, ask me again when it has a complete run?
- Fallout (2024 – Present): While video game adaptations usually embarrass themselves, Fallout turned out to be one of the best debut seasons of 2024 because it understood the source material well enough to translate it beyond just the plot. But even this one’s a hatchling, so it’s too early to rank definitively.
‘Doctor Who’ (2005 – Present)
The TARDIS Goes Everywhere and Keeps Finding New Things to Say.
The achievement of the 2005 Doctor Who revival is easy to underestimate in retrospect. I mean, Russell T Davies brought back a canceled 1963 franchise, modernized it without condescending to its original audience, and created something that has now run for over 20 years across multiple Doctors, showrunners, and tonal registers. It makes you wonder, what kind of show does Doctor Who want to be? If you ask me, it’s all of them. I particularly loved David Tennant’s era for turning the mythology into something that cracked a generation open.
Watch This If: You want a science fiction show that can do horror, tragedy, farce, and philosophical weight in consecutive episodes without any of it feeling inconsistent, because Doctor Who has been doing it reliably for two decades.
Skip This If: Tonal consistency is non-negotiable for you. Doctor Who’s greatest strength is also its greatest weakness. It is famously uneven across its run, and the gap between its Doctor Who‘s best episodes and its worst is wider than almost any show on this list.
‘Rick and Morty’ (2013 – Present)
Easily the Smartest Show on TV, but Will It Admit That? No.
I used to think Rick and Morty was mostly an excuse to cram as many sci-fi ideas as possible into 22 minutes. I rewatched it and realized that the older I get, the less I see a show about portals, alternate realities, and cosmic absurdity. Now it’s a show about deeply unhappy people trying (and usually failing) to connect. While the sci-fi backbone is still brilliant, it’s become almost secondary. The real thing is the coherent and bleak cosmology in which intelligence is a curse, meaning is self-imposed, and the family unit is simultaneously the source of the most profound pain and the only thing worth protecting. If that’s not relatable, I don’t know what is. I’ve lost count of how many times I’ve revisited episodes like “The Ricklantis Mixup,” “Total Rickall,” or “Auto Erotic Assimilation.” They manage to be hilarious, devastating, and intellectual at the same time.
Watch This If: You want animated sci-fi that treats its audience as adults, emotionally and structurally, without ever letting the “science” get in the way of the humor.
Skip This If: You need a show to take itself seriously. Rick and Morty is constitutionally incapable of that. If you’re not on board with the tone inside the first three episodes, trust me, it won’t get better.
‘Firefly’ (2002 – 2003)
14 Episodes Are Clearly Not Enough.
Firefly is the great unmade argument for what a five-season Joss Whedon sci-fi Western could have been. The fact that Fox canceled it before its first season finished airing has given it a cultural afterlife that’s more durable than most shows that ran for a decade. I’m always surprised at how quickly the crew feels familiar. You know them well enough to immediately understand who would sit next to whom at dinner, who would start an argument, and who would finish it. That chemistry is the show’s secret weapon, and Nathan Fillion’s Mal Reynolds holds it all together. The 2005 movie, Serenity, gives the story a conclusion of sorts.
Watch This If: You can handle a show that ends mid-sentence and will make you irrationally angry at a network executive you’ve never met. Also, if you love ensemble chemistry above anything else in fiction.
Skip This If: Closure is important to you. Firefly doesn’t have any, and Serenity helps give you catharsis without quite typing up the loose threads. If you go in, go in knowing that the unfinished story will haunt you.
‘The Expanse’ (2015 – 2022)
The Most Scientifically Honest Science Fiction Show Ever Made. It’s Also Just Really, Really Good.
Hard science fiction is the genre’s most demanding corner. It insists on internal physical consistency and refuses to hand-wave anything for dramatic convenience, and The Expanse is proof. Six seasons, a Syfy cancellation, an Amazon rescue that became its own cultural moment, and a finale that closed the story on its own terms. The show builds a solar system that feels inhabited, thanks to the Belters’ Creole language, the politics of Earth, Mars, and the Belt, and the physics of inertia and thrust deployed into the drama. Then it populates the story with characters whose problems feel persistently human. What I remember the most isn’t the Epstein Drive or the protomolecule. It’s Naomi Nagata trying to hold herself together. It’s Amos Burton deciding what kind of man he wants to be. It’s Chrisjen Avasarala treating diplomacy like a contact sport.
Watch This If: You want sci-fi that respects your intelligence on every level and that crafts its world through behaviour and detail rather than exposition.
Skip This If: You need an easy entry point. The Expanse drops you into a fully formed solar system and trusts you to orient yourself. The first three episodes require patience. After that, it earns everything it asks.
‘Orphan Black’ (2013 – 2017)
One Actor. Eleven Characters. Zero Bad Episodes.
I know it’s been over a decade, but there was a point during Orphan Black Season 2 where I stopped consciously registering that Tatiana Maslany was playing all of these characters. That sounds ridiculous. It is ridiculous. However, somewhere between Sarah, Cosima, Alison, Helena, and Rachel, my brain stopped seeing an actress performing multiple roles and started treating them like separate people who happened to share a face. I’ve never had that experience with another sci-fi show, and J.K. Simmons’ Counterpart happens to be among my favorites. The thing I remember most, though, isn’t the cloning conspiracy. It’s the dinner parties, the arguments, and the character choices that make every clone feel real. The Emmy voters ignored Maslany for three years before the lobbying campaign from the show’s fanbase became impossible to dismiss, and she won an award in 2016.
Watch This If: You’re interested in questions of identity, bodily autonomy, and corporate ethics wrapped in a thriller that moves fast enough that you won’t realize how much you’re thinking until the episode ends.
Skip This If: You need strong sci-fi world-building as a prerequisite. Orphan Black is grounded in near-future reality, and its science is functional, not exploratory. The genre elements serve the character study, not the other way around.
‘Mr. Robot’ (2015–2019)
A Hacking Show Where Hacking Is a Metaphor for Something Bigger.
Before Mr. Robot, Rami Malek was primarily known as a pharaoh’s tablet in Night at the Museum. The gap between that and Elliot Alderson, a cybersecurity engineer with dissociative identity disorder, social anxiety, and a plan to cancel all global debt by hacking the world’s largest conglomerate, is one of the great before-and-after career transformations I can think of. It led directly to an Emmy, a Golden Globe, and eventually an Oscar for Bohemian Rhapsody. But Sam Esmail’s formal ambition is worth looking at here. Entire episodes are shot in single takes, Season 2 withholds its own central plot for half a run, and a Season 3 episode recreates the grammar of a 1970s movie in real time. The hacking is accurate, and the politics are earnest. Mr. Robot is still a show about loneliness, alienation, trauma, and the impossible fantasy of fixing a broken world through sheer force of will.
Watch This If: You want a show that uses science fiction as a tool for political and psychological seriousness. A show that’s also formally inventive enough to make the medium itself part of the argument.
Skip This If: Unreliable narrators test your patience. Mr. Robot builds its entire architecture on Malek’s unreliable protagonist, and Season 2 specifically will frustrate viewers who feel the show is withholding rather than building. However, I can assure you it’s building. Just stick with it.
‘Stranger Things’ (2016 – 2025)
Arguably the Most Influential Streaming Show Ever Made. Argue With the Duffer Brothers, Not Me.
I don’t think people fully understand or appreciate how difficult it is for a TV show to become a cultural phenomenon now. Television doesn’t work the way it did 20 years ago. Everybody watches different things. Algorithms have fragmented audiences into tiny communities, and shared experiences are very, very rare. Netflix’s Stranger Things debuted in 2016, and suddenly, everybody was watching the same show again. Parents. Teenagers. People who hadn’t thought about Dungeons & Dragons in three decades or so. People who had never played it.
Stranger Things sometimes gets dismissed as an exercise in nostalgia, and I understand the criticism. I’ve even made it myself. But nostalgia alone doesn’t keep a series alive for nearly a decade, and it certainly doesn’t move a series up the charts to draw 140.7 million views and become the third most-watched series in Netflix history. More importantly, the Duffer Brothers have created the template for streaming sci-fi by making you clear your weekend and talk about Stranger Things on Monday with unmatched urgency.
Watch This If: You want the definitive example of how streaming changed the cultural relationship between television and its audience, with the added benefit of witnessing one of the genre’s most satisfying ensemble casts do their thing.
Skip This If: Nostalgia-driven storytelling leaves you cold. The ‘80s references aren’t incidental to Stranger Things; they’re the show. If that’s not your frequency, Stranger Things will do nothing for you.
‘Battlestar Galactica’ (2004 – 2009)
Ronald D. Moore Spent Years Inside the Star Trek Machine… Then He Burned It Down.
Ronald D. Moore left the Star Trek writers’ room convinced that science fiction television was capable of more: more moral ambiguity, more political seriousness, and more willingness to let characters do genuinely terrible things and bear the full weight of them. He made that argument with Battlestar Galactica, a space opera that arrived in the years after 9/11, when the TV landscape was full of questions about security, power, and what people are willing to justify when they’re scared. Underneath the spaceships and Cylons is a series wrestling with some very uncomfortable things. Edward James Olmos as Adama and Mary McDonnell as President Roslin anchor a cast that includes Katee Sackhoff, James Callis, and Michael Hogan. It’s as close to perfect as sci-fi can get.
Watch This If: You want a show that proved science fiction could carry the weight of serious political and moral drama, not as an allegory you have to decode, but as immediate, visceral storytelling about people in impossible situations.
Skip This If: You need narrative closure. The finale is divisive and controversial in ways that have not softened with time. This is a warning.
‘Severance’ (2022 – Present)
What if Your Work-Life Balance Was the Problem, Not the Solution?
Severance is the most precise show on the list. It’s the one I find it hardest to stop thinking about, and the one whose central premise does all the philosophical work. The procedure that bifurcates workers’ consciousness so that the person who clocks into Lumon Industries has no memory of the person who goes home at night is pure science fiction. However, the show uses it to ask questions that have nothing to do with technology. What is your identity? What constitutes a life? Can a life of pure work or pure leisure be called a life at all?
Severance is also obsessed with space. That sterile, fluorescent corridor where Mark walks to the elevator, where every step feels too quiet, too controlled, makes you catch your breath. I’ve worked enough “normal” jobs to recognize this DNA. The meetings that should’ve been emails, the vague corporate rituals nobody fully understands but in which everyone participates, are all there. The show removes the escape hatch and doesn’t allow a commute home to reset your brain. And the worst part is how familiar it all feels, even without the sci-fi.
Watch This If: You want a show that uses a science fiction premise to ask urgent, brain-scratching questions about work, identity, and autonomy.
Skip This If: You need answers on a reasonable timeline. Severance is a slow-burning mystery that deliberately withholds many things. If that’s not your relationship with television, and if you’re not a patient person, Season 2’s finale specifically will test you.
‘Black Mirror’ (2011 – Present)
Charlie Brooker Has Been Predicting the Future Since 2011, and the Man Is Never Wrong.
The case for Black Mirror at #1 is cumulative. No other show on this list has changed the way people talk about technology, the future, and the relationship between the two with the same consistency, across the same span of time, to the same global audience. I still remember watching “Nosedive” and thinking it was exaggerated. A world where your social interactions are constantly rated? Where politeness becomes performance? Where your “score” determines your access to life itself? It’s not really satire, because years down the line, we have let social media do that for us. The pattern is: Black Mirror shows you something uncomfortable, you dismiss it as extreme, and then slowly, the real world closes the gap. The weaponization of deepfakes in “The Waldo Moment,” the grief technology in “Be Right Back,” and the psychological dynamics of online pile-ons in “Hated in the Nation” feel all too real now.
Watch This If: You want the show that has most consistently used science fiction as a lens for the present. A show that has been doing it for 15 years and keeps finding new angles. Start with “San Junipero,” “Common People,” or “USS Callister,” depending on your mood.
Skip This If: You’re already anxious about technology and don’t need help. Black Mirror is not a comfort watch. In fact, it’s the very opposite of a comfort watch.
