The biggies
Ahsoka (Disney+, Wednesday, 3:01 a.m.)
It’s Rosario Dawson’s time to shine in Star Wars land as Ahsoka finally premieres. Jon Favreau and Dave Filoni’s show centers on Ahsoka Tano, who made her live-action debut in The Mandalorian’s second season. She gets her own spin-off now in which she investigates an emerging threat to the galaxy following the fall of the Empire. Natasha Liu Bordizzo, Mary Elizabeth Winstead, Ray Stevenson, David Tennant, and Lars Mikkelsen co-star. The A.V. Club will recap the show weekly.
Riverdale (The CW, Wednesday, 9 p.m.)
Will television ever be as fun as it was during Riverdale’s seven-season run? Say what you will about The CW’s bizarre teen drama, but Riverdale always embraced the chaos and knew exactly how silly it was. For that and more, it will be missed because the show is finally ending. In the series finale, the gang is out of the ’50s and back in the present day, with or without their memories restores. And in the future, an 86-year-old Betty (Lili Reinhart) wishes to relive her last day of senior year. Knowing Riverdale, which has survived a comet and multiple universes, anything can happen.
