1) “Independent Lens,” 10 p.m., PBS (check local listings). Meet stars of TikTok – Spencer X. a beat-boxer with a million-dollar mouth … Deja Foxx, once a homeless teen and now a Columbia honors student who supports herself and her mom with videos ranging from sexy to socio-political … Feroza Aziz (shown here), who slid genocide protests into an eyelash tutorial. We also hear about chilling TikTok sins, from censorship to shaping youths with subtle biases.
2) “9-1-1,” 8 p.m., Fox. In some of its better moments, this show has flashed back to see how its key characters got here. Now it views the relationship between Hen and her wife, Karen. That comes during a key time: Karen took Hen’s son Denny to her lab; there’s a crisis and Hen leads the rescue attempt.
3) “Quantum Leap,” 10 p.m., NBC. On Oct. 17, 1989, rush hour was lighter than usual in the Bay area; many people had left early, to catch a telecast of the World Series game between neighboring San Francisco and Oakland. Then an earthquake struck at 5:03 p.m. It killed 63 people (42 of them when an Oakland freeway collapsed), damaged 12,000 homes and delayed the Series for 10 days. Here’s a fictional view, with Ben dumped into the midst.
4) “Doc Martin,” any time, www.acorn.tv. Even this dependable show can get too goofy. That happens in the first new episode tonight; a guest character (running a survival course) is overblown. Not to worry, the other episode is excellent, as Doc clashes with a new herbalist. This also has Lesley Nicol – the likable cook on “Downton Abbey” – as a widow who savors the water. Also, “My Life is Murder” has two new episodes, one Christmas-themed.
5) “Dancing With the Stars,” 8 p.m., Disney+. It’s Michael Buble night. He opens the show by singing “Sway,” with the professional female dancers performing. Later, his “Higher” is performed by Derek Hough, Hayley Erbert (Hough’s fiance) and the pros. Joining Hough and others as a judge, Buble sees 10 couples dance to his songs, including “Come Fly With Me” and, of course, “Come Dance With Me.”
