1) “Star Trek: Discovery” first-season finale, 10 p.m., CBS. Here’s what the previous 14 episodes have led to – an attempt to end the fierce war with the Klingons. Burnham (shown here) is in a tiny landing party with Ash (who still has memories as a Klingon) and Georgiou (whose intentions are iffy). The result has high stakes, great visuals and excessive violence against a helpless prisoner. It also has stiff dialog; you get that when your main character was raised by Vulcans. The next seasons are already on CBS All Access.
2) Movies, cable. Here’s a Black History Month night worth recording. HBO has “Harriet” (2019), the Harriet Tubman story, at 10 p.m.; Showtime has a Spike Lee double-feature. At 9 p.m. is “Do the Right Thing” (1989); the American Film Institute puts it at No. 96 on its all-time list, ahead of “Toy Story,” “Blade Runner” and more. At 6:50 p.m. is “Mo Better Blues” (1989), starring Denzel Washington – who also stars in “Equalizer 2” (2018), at 8 and 10:30 p.m. on FX.
3) Comedy reruns, 8-9:30 p.m., CBS. The rerun siege will finally end next week. For now … well, “B Positive” (8:30) is running an episode (a good one, actually) for the third time in just 11 weeks. There are also reruns on “Young Sheldon” at 8 (a Dungeons & Dragons game) and “Mom” at 9 (a sober retreat). Fortunately, “Mom” had been using shows from last year, when Christy was still there.
4) “Mr. Mayor,” 8 p.m., NBC. With CBS tied up in reruns, NBC has had new episodes of this clever (but inconsistent) comedy, co-produced by Tina Fey and starring Ted Danson as a well-meaning mayor. Tonight, a mandatory meeting complicates schedules.
5) “Law & Order: Special Victims Unit,” 9 p.m., NBC. Here’s a rerun of the season-opener, an episode that reflects the way police shows becoming more reflective. Investigating an assault in Central Park, the unit finds that the community is losing trust in the police.
