‘Happy Valley’ Final Season, ‘Jeopardy! Masters’ Semi-Finals, ‘NCIS’ and More Finales (‘A Small Light’), Prehistoric Planet

Winner of multiple BAFTA awards for its first two seasons (available for streaming on Acorn), the acclaimed British crime drama returns after seven years for a third and final season. Sarah Lancashire (Julia, Last Tango in Halifax) is tremendous as soon-to-retire Sgt. Catherine Cawood, a tough but compassionate Yorkshire cop who has seen the worst of human nature, distilled in the monstrous criminal Tommy Lee Royce (Granchester’s James Norton). Watch out should she learn that Tommy has found a way to connect from his prison cell to his son, and her beloved grandson, Ryan (Rhys Connah), now an impressionably curious teen. Like Broadchurch and other modern classics of the genre, Happy Valley packs an emotional as well as suspenseful punch.

The 20th season ends with agent Nick Torres (Wilmer Valderrama) in prison—which most likely has to do with the fact that someone behind bars has intel on an impending terror attack in the U.S., but the mission also conjures personal demons from Torres’ past. In happier news, NCIS historian Ducky (David McCallum) is back for the finale. And while franchise fans may be mourning the end of NCIS: Los Angeles over the weekend, NCIS has been renewed for a 21st year, and its Monday night companion NCIS: Hawai’i (10/9c) will be back for a third. In the Hawai’i finale, Tennant (Vanessa Lachey) hunts for a killer with a personal vendetta.

The moving and devastating final chapters of the historical docudrama are, by necessity, tragic once Nazis discover the family of Anne Frank and their friends in the secret annex in August 1944. For Miep Gies (a remarkable Bel Powley), the brave Austrian-born Dutchwoman who helped hide the Franks in Amsterdam, the crusade isn’t over yet as she takes desperate measures to try to buy their freedom. The coda, when Otto Frank (Liev Schreiber) returns as the sole survivor, is heartbreaking yet also uplifting upon his discovery that Miep saved Anne’s diary, which will go on to inspire generations.

This exciting tournament of top Jeopardy! players moves into the final stretch, with James Holzhauer (relishing his “game show villain” persona), Andrew He, Matt Amodio and Mattea Roach competing in four games over two nights to decide who’ll make it into Wednesday’s two-game finals. (Sorry, Amy and Sam.) No one appreciates good game play more than host Ken Jennings, whose banter with James is so juicy it might make you wish for a Greatest of All Time rematch. The “Daily Doubles” are particularly important in this round, with big bets and dominant performances from Holzhauer and He in particular.

Spend the week in a dazzling Jurassic world, with episodes dropping daily (through Friday) from the second season of the natural history docuseries that recreates a world inhabited by a wide array of dinosaurs. Sir David Attenborough narrates, with experts from the BBC Studios Natural History Unit and visual effects from the creators of The Lion King and The Jungle Book remakes. Each of the five new episodes imagines a different environment: islands, volcanic badlands, swampy marshlands, deep oceans and North America, home to the fearsome T. rex. This is nature programming taken to the next level.
