1) “Saturday Night Live,” 11:29 p.m., NBC. This wraps up the opening string of three new “SNL” shows. The opener (hosted by Miles Teller) was disappointing, the second (Brendan Gleeson) was better, with both at their best during “Weekend Update” and the films. Doubling as tonight’s host and music guest is Megan Thee Stallion (shown here), 27, the first woman to win Grammys for best rap performance and rap song; she also won best new artist.
2) “The Disappearance of Cari Farver” and “Let’s Get Physical,” 6 and 8 p.m., Lifetime. Both are true-crime tales, produced by Kelly Ripa and her husband, Mark Consuelos. In the first (which debuted last Saturday), the tone is dark, as a guy receives thousands of threatening e-mails from his missing ex-girlfriend. The second is surprisingly light and bright, with Jenna Dewan as a small-town dance and fitness instructor who adds sex to her services.
3) “Queen Elizabeth II: The Woman Behind the Crown,” 8 p.m., CW. This “Entertainment Tonight” special, hosted by Kevin Frazier, aims for a personal view of the late queen, including her humor and her 74-year marriage. It includes interviews with palace staff and with stars who know her.
4) “East New York,” 8 p.m., CBS, and “The Winchesters,” 9 p.m., CW. If you missed these openers, here’s a chance to catch up. The CBS show, from “NYPD Blue” producers, tries to do a lot with some success, as a precinct commander starts her first day on the job; the second episode follows at 9. “Winchesters” confines itself to one well-told story – the 1972 moment when the parents of the “Supernatural” brothers met while smiting demons.
5) “Who the (Bleep) Did I Marry?” season-opener, 10 p.m., ID. Starting its seventh season, this keeps finding marital disasters. In this case, Kris Johnson had a seemingly enviable marriage: Lt. Col. James Johnson, an honors graduate of West Point, commanded the 173rd Airborne Brigade Combat Team. During a New Year’s Eve weekend with house guests, she discovered a long and complex relationship with a woman he met in Iraq.
