1) “Resident Alien,” 10 p.m., Syfy. This clever gem seemed simple at first: An alien (shown here) arrived to kill all Earthlings, but lost parts of the device he needs. To buy time, he killed Harry (a reclusive doctor) and assumed his human form; the mayor’s son is the only one who sees through his disguise. Then the twists began: Last week, Harry’s wife arrived; now we meet the town’s new doctor, plus an obsessive general (Linda Hamilton of “Terminator” fame). There’s humor, as usual, and then a dramatic finish.
2) “Good Trouble,” 10 p.m., Freeform. The two central characters again find their lives in turmoil. Callie confronts complications in a seemingly simple court case; Mariana finds it was easier to quit her job than to quit her romance with the boss. But this hour – a good one – also focuses on two of the other women: Alice feels like an outsider at a comedy workshop; Davia struggles as a teacher, amid possible romances – a nearby colleague and the far-away Dennis.
3) “Name that Tune,” 8 and 9 p.m., Fox. Here are the final episodes of this show, which has Jane Krakowski as host and Randy Jackson as music director. “The Masked Singer” returns next week, leading into the debut of the new “Game of Talents.”
4) “The Conners,” 9 p.m., ABC. Roseanne’s memory lingers, even though the character has died. Tonight, her sister visits the grave and is appalled by the next headstone. Also, Mark worries that he has COVID. And Harris doesn’t know why Josh ignores her; she and her Aunt Becky confront him.
5) “Farmhouse Fixer” debut, 9 p.m., HGTV. When their band isn’t together, the New Kids on the Block range afar. Donnie Wahlberg and Joey McIntyre are busy actors … Danny Wood and Jordan Knight focus on music … and Jonathan Knight (Jordan’s older brother) fixes houses. He’s done more than 200, HGTV says; now he’ll focus on farmhouses. He’ll start with a New Hampshire one from the 1700s, including removing a sinking addition and turnng a tool shed into a potting bench and chicken coop.
