Supergirl

"Supergirl" started back on CBS and moved to the CW with it's second season, which is probably where it should have been all along. Each season, the show has gotten better and better. "Supergirl" has always had the best ensemble of all the Arrowverse shows, but sometimes its earnestness was its greatest strength and its greatest weakness. Last season, the show really seemed to find its groove. The fantasy genre, from sci-fi, superhero, etc, likes to use it's fantastical storytelling to mirror real life issues and "Supergirl" did a great job of taking on Trump's America with its aliens as immigrants allegory. Ben Lockwood's fanaticism was meant to evoke Trump's followers.
When we left Kara and company, Lena had murdered her brother, Lex, but not before he revealed that Kara was Supergirl.

The Monitor brought Lex back to life and brought J'onn's brother to exact some sort of revenge. Eve Tessmacher was approached by a representative from a group calling themselves Leviathan.
