... Superman is an alien. Wonder Woman is like, some kind of heir to being a goddess. They don't really have the best backstory.
Completely irrelevant. Captain America is a super-steroid-freak, and Thor isn't just an heir
to a goddess, he's a full-on god.
There's nothing wrong with DC's characters. The only problem they have is that they've made a few mediocre or crappy movies in Superman and Green Lantern, and have been too timid about bringing other projects to fruition.
