Agree. I hope S:WOT is a two-part film with Supergirl returning to Earth at the end of the film setting up a quick follow-up. Gunn's crowded schedule doesn't allow for many more films in Phase 2, but fingers crossed a Supergirl sequel has been penciled in. It may feature Brainiac (Supergirl projects have been rumored to do that including a Cavill Supergirl/Superman film back a few years) and it may be that Supergirl will be the film vehicle to introduce classic villains like Brainiac and Metallo.
