Prepare for a Cruel Summer

Here’s what’s happening in the world of television for Tuesday, April 20. All times are Eastern.
Top pick
Cruel Summer (Freeform, 9 p.m., series premiere, back-to-back episodes): Who doesn’t want a little psychological thriller in their diet now and then? It’s good for the digestion—and if it comes with some ’90s fashion flashbacks, so much the better.
Freeform’s latest, which comes from executive producer Jessica Biel (who was also an EP for The Sinner), centers on a geeky teenager (Chiara Aurelia) who transforms into a popular America’s Sweetheart type following the disappearance of the town’s previous queen bee (Olivia Holt). Its story spans three successive summers, is told through shifting points-of-view, and is all-but-guaranteed to have a killer soundtrack. What more could a TV viewer want? Perhaps only to read Saloni Gajjar’s pre-air review, which will appear on the site later today. And a quick heads-up: After this week’s double-length premiere, the show will air at 10 p.m. on Tuesdays.
Regular coverage
Supergirl (The CW, 9 p.m.)
Big Sky (ABC, 10 p.m.): time-slot premiere
