is about how our normal world is invaded by denizens of a more fantastic one, and Diana's job (apart from all the political stuff) is to keep us safe from the various war gods, werecat-brides of plant gods, and ancient sorceresses that are out to dominate us. Both in-text and metatextually, she's meant to bridge between myth and the mundane.
That type of Thor film sounds interesting, but I'm more intrigued if it ends up being helmed by Matthew Vaughn. A fantasy-filled Thor film directed by Vaughn piques my interest a lot.
Vaughn left the project, as far as I know (he's not one for commitment to his superhero projects, it would seem); the original script, from what I've heard, is basically all-Asgard. Of course, once it's been rewritten to be half as expensive, who knows?
