1) “CSI: Vegas” debut, 10 p.m., CBS. Six years after “CSI” ended – and 21 years after it began – it’s back. There’s a new name, a new lab and a new set of regulars. Still, the others are also there: We see Brass in the first scenes, Grissom in the final seconds. Sidle (shown here, second from left) is busy; Hodges will be key in the weeks ahead. The newcomers are fairly interesting, with the always-great Mel Rodriguez as the chief medical examiner. They solve a case-of-the-week way too easily, leaving more time for a tangled, ongoing case.

1) “Rita Moreno: Just a Girl Who Decided to Go For It,” 9 p.m., PBS. At 5, Moreno moved with her mother from Puerto Rico to Long Island. She took dance lessons, was on Broadway at 13, signed a movie deal as a teen … and endured stereotype roles. The exception was “West Side Story”; she won an Oscar, vowed to wait for good roles … and didn’t do another movie for seven years. She survived that (and a toxic romance with Marlon Brando) and is still working at 89 (shown here). It’s a great story. Read more…

1) “9-1-1,” 8 p.m. , Fox. Los Angeles life has been rough lately. The season’s first episode had a ransomware attack; the second had a citywide blackout. Now the blackout continues; the rapist who attacked Athena (Angela Bassett,shown hee in a previous episode) has escaped; Athena races to protect her family. And Maddie (Jennifer Love Hewitt), struggling with postpartum depression, makes a big decision. Read more…

1) “Grantchester” season-opener, 9 p.m., PBS. On one level, this is an uncommonly bright hour: The crimesolving vicar vacations at a summer resort with his housekeeper (plus her husband), his curate (plus his secret lover) and his Geordie (they’re shown here) the cop (plus wife and kids). A solid murder mystery ensues – while planting the seeds for wrenching moments in the weeks ahead. There’s a lot of that sometimes; the “Call the Midwife” season-opener, at 8 p.m., is exceptionally grim. Read more…

1) “Saturday Night Live” season-opener, 11:29 p.m., NBC. As rumors swirled, fans feared the worst. Maybe Kate McKinnon was leaving … or Cecily Strong … or Kenan Thompson. But all three are back for this 47th season; only Beck Bennett and Lauen Holt are leaving. Bowen Young and Chloe Fineman move up to the main company, with three newcomers added. Owen Wilson (shown here) hosts the opener, with Kacey Musgraves as music guest. Read more…
