Oh as a comic fanboy, I know all about the Supergirl show and my hopes aren't high. I don't think kids really care about Supergirl enough. I barely see any interest in Wonder Woman anymore. j'onn j'onzz Is popular with peope my age but again, the kids doesn't seem to care about him. Heck, since the Man of Steel film and lack of a legit role in The Lego Movie,, ids don't seem to really care much about Superman. Zack Synder is terrible. Everything is Batman, Avengers, and Spider-Man.
By the way. The Flash and Arrow (since season 2) shows are done well. Maybe Supergirl stands a chance. I'm just staying away from this set except for one if my son ever asks for it (and he likes Superman).
