1) “Best Medicine,” 8 p.m., Fox. With this show’s format, anything is possible. Things can be goofy — sometimes too goofy — one moment, serious the next. This time. that leans mostly to the serious side. The story starts with a spinster who loves great birds and bad poetry, then (shown here) has a disaster. From therem it spins in many interesting directions.
2) “RJ Decker,” 10 p.m., ABC. Decker is a private detective, but his prison days linger. Now a former cellmate wants help clearing a late friend’s son; it gets messy. That’s preceded by “Will Trent” at 8 (murder of a fraternity guy) and “High Potential” at 9 (attempted murder of Daphne’s mentor).
3) “NCIS,” 8 p.m., CBS. Big-time dangers ripple through this show and its prequel: In “NCIS,” a man has barricaded himself inside an ammunition warehouse. In”NCIS: Origins,” at 9, an officer arrives with what may be a deadly virus, forcing a quarantine.
4) “The Count of Monte Cristo” (2024), 5-8 p.m., MGM+. Some 180 years after it was written, this tale of persecution and revenge still works. It’s been filmed 40-plus times; this French film drew praise for its lush visuals. The same could be said for a six-parter that debuts March 22 on PBS.
5) More movies. On the fun side, try “School of Rpck” (2003), at 8:20 p.m. on Paramount+ or “21 Jump Street” (2012), 7:05 p.m., on Showtime. On the grim side, “Fukishama” (2026), 9 p.m. on HBO, tells of the 2011 Japanese meltdown, considered the worst nuclear disaster since Chernobyl in 1986.
