Supergirl HOW/WHEN & WHERE TO WATCH: 9 p.m. on The CW Season PremiereThe sixth and final season of Supergirl will test Melissa Benoist's titular hero like never before. "She is going to really sacrifice her life and put her life on the line to save her friends and humanity," co-showrunner Jessica Queller recently told EW. "That challenge, she's going to face her mortality in a way we've never done on the show. That's really the focus of the first run of seven episodes. It's life or death stakes for Kara, and it's very introspective. So, all of the soul searching and taking stock of the past six years will happen in the beginning, and then she'll put it all into play in the second half." In other words, Supergirl isn't going silently into that gentle night. —Chancellor Agard Related content: Supergirl bosses preview Lena's new role and 'life or death stakes for Kara' Supergirl star Azie Tesfai reveals how she came to write an 'epic' Kelly episode Supergirl casts young Cat Grant for final season flashback episodes What ELSE to Watch Check local listings American Experience: The Blinding of Isaac Woodward — PBS The Place That Makes Us (doc) — World Channel/PBS app platforms 8 p.m. The Flash — The CW Women Making History (special) — Lifetime Young Rock — NBC Queen Sugar — OWN 8:30 p.m. Kenan — NBC 9 p.m. Black-ish — ABC The Real Housewives of Dallas — Bravo The Last Cruise (doc) — HBO Unsellable Houses (season premiere) — HGTV This Is Us — NBC Our OWN Easter (special) — OWN 9:30 p.m. Mixed-ish — ABC 10 p.m. Soul of a Nation (guest host Jemele Hill) — ABC Mayans M.C. — FX New Amsterdam — NBC Streaming Glad You Asked (season premiere) — YouTube Demi Lovato: Dancing With the Devil (part 3) — YouTube Movies Make|SHIFT (doc) — Digital Like a House on Fire — Digital *times are ET and subject to change We know TV has a lot to offer, be it network, cable, premium channels, or streaming platforms including Netflix, Disney+, Hulu, HBO Max, Amazon Prime Video, Apple TV+, and others.
