1) “Young Sheldon” season-opener, 8 p.m., CBS. Gradually, this has become less about Sheldon and more about his quirky clan. Now that peaks as the final season begins, with Sheldon and his mom in Germany. They bring some good moments, but the best ones are back home, where a tornado flattened his grandmother’s house. Now she’s wedged in (shown here) with the rest of the crowd, including Sheldon’s dad, siblings, baby niece and more.
2) More season-openers, CBS. “Ghosts” (8:30) answers the key question: Which ghost was whisked away at the end of last season? It’s a fairly good episode; so is “So Help Me Todd” (9 p.m.), despite trying too hard. Todd has finally regained his detective license and his ambitions. The result is frantic and, at times, funny.
3) “Genius: MLK/X,” 9 and 10:09 p.m., National Geographic Channel, rerunning at 11:20. The first hour focuses on Coretta Scott King and Betty Shabazz, two bright and talented people (an operatic soprano and a teacher and nurse) who may have been underrated by the world – and by their husbands. The second returns to triumphs, including the march on Washington.
4) “Truth & Lies,” 8-10 p.m., ABC. Warren Jeffs grew up as the son of a leader of a fundamentalist variation of the LDS church. When his father died, he reportedly married most of the 20 widows. The breaking point came when men in the cult married girls who were 15 or younger; Jeffs faced rape charges. This documentary looks back at a long battle in the courts.
5) Dramas, 10 p.m., With the extra-long Super Bowl on Sunday, many people might have skipped the “Tracker” debut – a good one – that followed. Now that hour reruns on CBS. Alternatives: A new “Law & Order: Organized Crime” (NBC) adds an artificial-intelligence approach to law enforcement; a “Will Trent” rerun (ABC) finds this loner temporarily taking care of a young boy.
