1) “NOS4A2” season-finale, 10 p.m., AMC and BBC America. Here’s the confrontation we’ve waited two years for. Vic (the terrific Ashleigh Cummings) hops on her motorcycle and heads off to rescue her son, shatter the twisted Christmasland (shown here) and confront Charlie Manx. All of that is tough, high-octane … and over fairly quickly. Then Vic must cope with real life, in what may well be the show’s final hour.
2) “Masterpiece: Endeavour” season-finale, 9-10:30 p.m., PBS. This short season – three movie-length episodes – has been disappointing. The opener scattered lots of disconnected things, leaving many of them open; the second episode mostly ignored them. Now, the third one sort of wraps them up. It does stretch credibility nesr the breaking point, but has skilled actors in grand settings.
3) “The Simpsons,” 8 p.m., Fox. It’s still rerun time – tonight, Lisa accidentally hangs around with the mean girls – but there’s good news ahead. Animation hasn’t been slowed much by the coronavirus; tonight’s Fox line-up – “Simpsons,” “Bless the Harts,” “Bob’s Burgers: and “Family Guy” – will have new episodes, starting Sept. 27.
4) “The Chi” season-finale, 9 p.m., Showtime, rerunning at 11:30. Lena Waith’s richly layered Chicago series offers its entire season tonight. Previous eplisodes are 11 a.m. to 8 p.m.,, followed (after a break for “The Circus”) by the finale. Another example of Waithe’s writing is “Queen & Slim” (2019), at 6:40 p.m. on HBO; it’s the story of a date that turns into a national incident.
5) And more. Also with season-finales are Kevin Costner’s “Yellowstone” (9 p.m. on Paramount and CMT) and “Mayday: Air Disaster” (8 p.m. ET, Weather Channel, which has with the season-opener of “Weather Gone Viral” at 9). At 8 p.m., Freeform has the second half of “Love in the Time of Corona” (see “news and quick comments”); at 10, HBO starts “The Vow,” a nine-week documentary about NXIVM, an “executive success program” that led to sex-trafficking convictions. Movies range from “Gone With the Wind” (8 p.m. ET on Turner Classic Movies) to “Sharknado” at 3 p.m. on Syfy, with its sequel at 1.
