1) “SNL50: The Anniversary Special,” 8-11 p.m. ET, NBC. This live event (with red-carpet at 7) will be busy. It includes four of the first-year stars plus many that followed – Eddie Murphy (shown here), Will Ferrell, Kate McKinnon, Tina Fey, Amy Poehler, Jimmy Fallon, Seth Meyers, Kristen Wiig, Chris Rock and more. Also, Steve Martin, Tom Hanks and other hosts.
2) “The White Lotus” season-opener, 9 p.m., HBO, repeating at 10:03. The first season won 10 Emmys and the second (rerunning from 1:30-9 p.m.) added five more. Now the third season begins, this time in Thailand, with a few returning elements – writer-director Mike White, co-star Natasha Rothwell (Belinda in the first season) and an elegant resort.
3) “Miss Scarlet” season-finale, 8 p.m, PBS. All season, Eliza has been debating Inspector Blake, who distrusts private detectives. Now they work together, after one of his men is attacked. It’s a fairly good story, ending with a terrific moment; that leads into “All Creatures Great and Small,” which has a neat detour in the brothers’ relationship.
4) Animation, 8-10 p.m. With its deep bench of cartoons, Fox rests “The Simpsons” until March 30. Now it has belated season-openers: On “Family Guy,” a fairly clever “Top Gun” satire. On “Grimsburg,” a reminder that it’s a mixed blessing to live with the ghost of a ‘50s TV housewife. On “The Great North,” a local reality show, “Dropped Off to Die.”
5) ALSO: CBS finally has its Sunday dramas back, with new episodes of ratings-leaders “Tracker” (8 p.m.) and “The Equalzer” (10). In between is the second “Watson” episode; like the first, it’s sleek and smart, but emotionally distant. At 8 p.m. ET, TBS and TNT have the NBA All-Star Game and Turner Classic Movies has the splendid “West Side Story” (1961).
