1) “Fargo,” 10 p.m., FX; repeats at 11:01, 12:02, 1:03. Last week, we met a quiet Minnesota mom (Juno Temple) named Dot … her gentle husband … his rich and fearsome mom … and the North Dakota sheriff (Jon Hamm, shown here) who said Dot is his runaway wife. Now both sides prepare for a Halloween showdown that airs next week. As always, tonight has great dialog, beautifully played.
2) “A Murder at the End of the World,” Hulu. At a time when new, scripted shows are rare elsewhere, the FX people have produced two brilliant ones – “Fargo” for their own network (streaming on Hulu the next day) and this one directly for Hulu. Emma Corrin (the first Diana on “The Crown”) is superb as a young crimesolver. This episode bounces between a frigid crisis in Iceland and memories of her ex-boyfriend, who’s now a murder victim.
3) “Dancing With the Stars,” 8-10 p.m., ABC. A week from its finale, the show could have it second teen champion, both of them Latinas. Laurie Hernandez, 16, an Olympic gymnast, was the 2016 winner; now Xochiti Gomez, 17, the “Doctor Strange” co-star, is in the final five. She faces “Bachelorette” Charity Lawson, 27; Ariana Madix, 38, of “Vanderpump Rules”; singer Jason Mraz, 46; and actress Alyson Hannigan, 49.
4) “CSI: Sydney,” 8 p.m., CBS. A shark is hauling an arm that has a Navy SEAL watch; foul play is suspected. This episode spends a lot of time on its quirkiest staffer, some of it quite exaggerated. But the basic story, involving SEAL veterans, is fairly sharp and involving.
5) “FBI True,” 10 p.m., CBS. Chyenne Kircher was 14 when she disappeared; a note in her handwriting said not to look for her. Two years later, a new search found jarring answers. That’s on a busy night of non-fiction. At 8 p.m., NBC continues the “Voice” playoffs and CW has “Inside the NFL”; at 9:02, Fox has a “Kitchen Nightmares” rerun, with a woman who started an Italian restaurant with her three sons.
