1) “Masterpiece: Roadkill” opener, 9 p.m., PBS. We meet Peter Laurence (Hugh Laurie, shown here) in a moment of victory. He successfully sued a newspaper that accused him of corruption. All is fine … except the newspaper may have been right. Also, he’s cheating on his wife … he’s distant with his daughters … he’s surrounded by schemers … and there are big twists ahead. We don’t know whether to like or hate him; we still won’t know when the four-parter ends, but there are big surprises along the way.
2) “The Simpsons,” 8 p.m., Fox. “Treehouse of Horror,” the annual Halloween episode, finally arrives … on the day after Halloween. Delayed twice by baseball, it’s worth waiting for. After a funny election prologue, we get three tales – multiple Homers … Bart’s toys take revenge … and Lisa’s birthday turns violent – often. This is sometimes gory, but often clever. That’s followed by fairly good Halloween episodes of “Bless the Harts” (a haunted mall) and “Bob’s Burgters” (a creepy hotel room).
3) “The Comedy Store,” 10 p.m., Showtime. This five-parter concludes beautifully. Filmmaker Mike Binder (who was once a teen comic at the Store) assembles round-table of comedy veterans.They discuss it all, from bits that failures onstage and in life (Louie CK is interviewed) to the moment a startled emcee was told to introduce Chris Rock AND Steve Martin, preparing their Oscar-night jokes. This ends with warmly funny bits at the tribute to Mitzi Shore, the club-owner who died in 2018 at 87.
4) “Fargo,” 10 p.m., FX. At the same time that Rock is being funny on Showtime, he’s everything else – raging, fierce, mournful – on FX. The setting is 1950 Kansas City, with lots of period touches – from hats to great music – and a purely fictiional touch: To keep peace, the two gang leaders have exchanged sons. Meanwhile, Oraetta (the Minnesota transplant nurse, well-played by Jessie Buckley) continues her death toll. It’s a typical “Fargo” episode, bizarre but brilliantly crafted.
5) “Star Trek: Beyond” (2016), 8 p.m., CBS. Here’s the third “Trek” movie to star Chris Pine and Zachary Quinto as Kirk and Spock. It arrives on a great movie night – “BlacKkKlansman” (2018) at 7 p.m. on FX … “Silence of the Lambs” (1991) at 8 p.m. on Sundance … ”The Bourne Ultimatum” (2007) at 8 on A&E … and animated gems on Freeform: At 6:55 p.m. is “Frozen” (2013); at 9:25 is “Coco” (2017), which is set on the Days of the Dead – which, as it happens, are today and Monday.
