As with The Flash, Supergirl has costume choices that are head-scratchers (Why the blue in the S? Why a different S from the movie Superman?). As with the 1984 movie and the original comic, Supergirl has heavy doses of borderline sexism in the story elements, at least as presented in the trailer. But it looks like it has potential. It looks like it's being given an honest attempt at putting Kara Zor-El on the screen and making it believable. And if Berlanti's previous efforts are any indication, we can probably expect further elements from the comics to show up in ways that reflect the real world and the heritage of the character. I expect for a cat named Streaky and a horse named Comet to figure in eventually, but without the eye-rolling corniness of the 50s and 60s.
I still have no idea why WB/DC have decided upon multiple media universes for these characters, and only hope that Supergirl ties in either with the other TV shows, or with the universe established in Man of Steel. With Gotham already complicating things by being its own thing, it would be silly to make Supergirl come up it's own stand-alone world (CBS and the CW are owned by the same folks, after all). Unless they're setting up a multiverse event? Then, count me in!
