1) “The Simpsons: Treehouse of Horror,” 7 a.m. to midnight, FXX. Here’s a fun Halloween marathon. In random order, we get 34 half-hours of the annual cartoon (shown here); most have three weird shorts — sometimes gross, often funny, always imaginative. For more laughs, the original “Ghostbusters” is 3 and 8 p.m. on Bravo, with the sequel at 5:30 and 10:30; a 2016 reboot is 8 p.m. on TBS.
2) The dark side. And if you prefer scary stuff? The original “Halloween” (10:30 a.m. and 7 p.m., AMC) is well-crafted; the original “Friday the 13th” (7:15 a.m. and 7:45 p.m., IFC) isn’t. Also, BBC America has exceptionally good Stephen King films — “Misery” at 5:30 p.m. and “Christine” (from John Carpenter, the “Halloween” director) at 8.
3) “On Brand With Jimmy Fallon” finale, 8 p.m., NBC. This eight-episode run was crammed into three Tuesdays and five Fridays. Now four people remain; they make commercials for Therabody, with one winning $100,000.
4) “Sheriff Country,” 8 p.m., CBS. The main story involves a clever, small-town robbery. That partially nudges aside an ongoing story — which requires absurd behavior from most people — that has the sheriff’s daughter as a murder suspect. Next week, that one will (thankfully) conclude.
5) ALSO: At 9 and 10 p.m., CBS has new episodes of “Fire Country” (a zipline accident triggers a wildfire) and “Boston Blue” (a tense drug probe alongside Lena’s former police partner). And at 9, PBS has the second of its two hours from Texas Monthly; this one views “The State of BBQ.”
