1) “Masterpiece: Sanditon” season-opener, 9 p.m., PBS. More than two years ago, the first season ended with Charlotte’s life in flux. Her true love, Sidney Parker, had left to marry a rich woman, rescuing the finances of his brother’s shaky resort project. And now? Sidney isn’t back … nor is his sister … or James Stringer, who loved Charlotte from afar. But Charlotte is bringing her giddy sister and there are plenty of new guys, include redcoat soldiers (shown here). It’s a great start.
2) “An Audience With Adele,” 9-11 p.m., NBC. Four months after her wonderful CBS special, Adele is back, apparently with many of the same songs. This concert was taped at the London Palladium in November and offers a mix of her classic songs, plus ones from her new album, the first in six years.
3) “Call the Midwife” season-opener and “Before We Die” debut, 8 and 10 p.m., PBS. It’s a mixed night for PBS, with the splendid “Sanditon” surrounded by two oddly dark hours. “Midwife” is stuffed with good-hearted people, but this season keeps having them confront horrors; that starts with discoveries during demolition work. “Die,” adapting a Swedish thriller, is a grim cop show, propelled by an extreme coincidence.
4) “The Equalizer,” 8 p.m. or so, CBS. Yes, it’s still basketball-tourney time. But CBS – with games at noon, 2:30 and 5 p.m. — will give its 7:30 game to TruTV. That lets it catch a normal Sunday, starting with “60 Minutes” at 7 or so and then a key “Equalizer.” Dante was detained brutally by deputies, who didn’t realize he’s a fellow cop. He drifts into hallucinations about his childhood.
5) “Step Into … The Movies,” 10 p.m., ABC. A week before the Oscars, the talented siblings Derek and Julianne Hough re-imagine some of the great moments from “Singin’ in the Rain,” “Chicago,” “Dirty Dancing,” “Saturday Night Fever,” “Moulin Rouge,” “Beauty and the Beast” and more. Their guests have great skills in dance (Jenna Dewan), singing (Amber Riley) and both (Ariana DeBose).
