1) “Charmed,” 8 p.m., CW. As the final seven days of October begin, Halloween themes fill our TV sets. Few shows fit as perfectly as this smart-but-weird tale of three witches and their mentor. Chased by demons, they reached an alternate world, where only Macy still has her powers. Tonight, she ends up imprisoned alongside an intriguing new character (shown here). Also, Mel and Harry visit exotic dimensions. And Macy must find a new way to get a key card, after the one she swiped becomes useless.
2) “American Housewife,” 8 p.m., ABC. Here’s the start of an ABC tradition – a Halloween episode on each of the 10 comedies. It starts with Katie taking her daughter into a zombie-themed maze; she soon regrets it and sends for help. Then “Fresh Off the Boat” (8:30) has Louis still trying to convince his wife that this odd American holiday is fun. The other eight comedies will be Tuesday and Wednesday.
3) “Magnum P.I.,” 9 p.m., CBS. Even crime shows get caught up in the Halloween rush. At 8 p.m., “Hawaii Five-0” has a home-invasion on the holiday, with a “monster” emerging from the basement. And at 9, Magnum and Jin follow a bail-skipper to a Halloween bash; an escaped killer is also headed there, with Katsumoto in pursuit. Also, Higgins and Rick plan to spend the night at a house, to prove it’s not haunted. And TC and Kumu try to protect a sacred Hawaiian burial ground.
4) “American Masters,” 9 p.m., PBS. Money problems filled Mark Rothko’s life. He was 11 when his father died, a year after taking the family from Latvia to Oregon. Later, Yale rescinded scholarships for Rothko and two other Jews. And he once returned a commission he needed, because his paintings were going to an overpriced restaurant. That last part is dramatized in “Red,” the play PBS will air Nov. 15. This gorgeous documentary has snatches of that and an irony: A Rothko abstract sold for $86.9 million.
5) Also: It’s a big night on Netflix, with the second season of “The Kominksy Method”; in the first, Michael Douglas won a Golden Globe and got an Emmy nomination, for his portrayal of an acting teacher. It’s also a big one for baseball – the first time in 86 years that a World Series game is played in Washington, D.C. The game – the third in the best-of-seven series – starts at 8:07 p.m. on Fox.
