1) ”Janet Jackson,” 8-10 p.m., Lifetime and A&E; concludes Saturday. Merely with her music career, Jackson (shown here) would merit a documentary. She’s sold 160 million records; in the U.S., she’s had seven No. 1 albums and 10 No. 1 singles; among women, only Madonna and Mariah Carey have more. She’s also an actress (with an Oscar nomination) and has had a complicated life. She discusses the deaths of Michael and her dad, plus the Super Bowl controversy, three marriages, giving birth at 50 and more.
2) “Magnum P.I.,” 9 p.m., CBS. Moon Bloodgood, the former “Falling Skies” and “Code Black” star, plays a Supreme Court nominee who hires Magnum and Higgins when she’s being blackmailed. And with fatherhood looming, Rick suggests ways to make the bar more profitable.
3) “Blue Bloods,” 10 p.m., CBS. When Danny investigates a case, he soon finds that it’s one for his dad, the police commissioner: A cop who was attacked may have been corrupt. And Erin finds herself investigating the new woman in the life of her investigator, Anthony.
4) Movies. You can start the weekend with a superhero film – or several of them. TBS has the fun “Captain Marvel” (2019) at 8 p.m. and “Fantastic Four” (2015) at 10:26. FX has a “Spider-Man” triple-feature: The animated “Into the Spider-Verse” (2015) is 2:30 p.m., with “Homecoming” (2017) at 5 and “Far From Home” (2019) at 8.
5) “The Woman in the House Across the Street from the Girl in the Window,” Netflix. This film probably needed to skip movie theaters; its title wouldn’t fit on a marquee. It takes a familiar plot – someone may have witnessed a murder – and adds a twist: She’s been busy with alcohol and drugs and can’t be sure what she saw; Kiristen Bell stars. Also streaming today: Leslie Odom in the time-travel romance “Needle in a Timestack” (Amazon) and Tiffany Haddish in the eight-part comedy “The Afterparty” (Apple).
