1) “Fargo” season-finale, 10 p.m., FX. This hour is both fascinating and frustrating … which makes it typical “Fargo.” In 1951 Kansas City, Loy (Chris Rock, shown here) finds his life collapsing He’s barely clinging to his crime empire and has been told (incorrectly) that his son is dead. But last week, the mortician’s daughter showed what she had learned about a lethal nurse. That sets up tonight’s big moments – lots of them. This is brilliantly written and filmed, but we kind of wish it had a couple fewer endings.
2) “The Undoing” finale, 9 p.m., HBO. We know Jonathon (Hugh Grant) is a creep: Long ago, he showed no remorse after his little sister died on his watch; now he’s married to Grace (Nicole Kidman), but had an affair with Elena. Still, that doesn’t prove he’s a killer. As last week’s episode ended, Grace found – in their son’s instrument case – what looks like the weapon that killed Elena. Tonight, the trial continues.
3) “Coming to America” (1988), 9-11:30 p.m., CBS. The “NCIS” shows get a vacation, making room for one final round of CBS’ Sunday movie. Eddie Murphy stars as an African prince, looking for his queen-to-be in the U.S., with Arsenio Hall as his aide. Under director John Landis (who also did Murphy’s “Trading Spaces” and “Beverly Hills Cop III”), both Murphy and Hall play multiple roles.
5) “Ice Age: A Mammoth Christmas,” 8:30 p.m., Fox. Here’s one of the better Christmas cartoons. Sid (John Leguizamo) is told that he’s on Santa’s naughty list; his solution is to visit Santa and plead his case. That follows above-average cartoons at 7 and 7:30 p.m. on ABC; the “Prep & Landing” tales focus on Santa’s advance team. And there are new Christmas movies – 7 p.m. on Ion and 8 p.m. on Hallmark (with Candace Cameron Bure) and Lifetime (Vannesa Lachey and Patrick Duffy).
5) “Masterpiece: 50 Fabulous Years,” 8 p.m., PBS, repeating at 9:30. On Jan. 10, 1971, PBS began a mini-series about the lust and love of Winston Churchill’s ancestors. “The First Churchills” was followed by monarchs – Henry VIII and Elizabeth I. Now – six weeks before the 50th anniversary – the “Masterpiece” history is celebrated. There’s much to note, from “I Claudius” to “Downton Abbey” and beyond, “Masterpiece” has won 83 Emmys, 18 Peabodys and even two Academy Awards.
