I'll definitely say, as someone who defaults to disliking much of the superhero adaptations (though currently I'm 1 for 1 on TV shows - loving Jessica Jones, warts and all!), Marvel still does a bit better at being diverse in its genres, but it still isn't good. I want movies where the superhero setting is incidental rather than being the defining element of the show. The Avengers, to me, is a superhero movie, whereas GotG is a space opera about superheroes. I'm kind of rambling, but basically what I want out of superhero movies is for them to give each movie its own identity that sets it apart from the rest. So, how about a superhero movie in the horror genre? Or a very complex sci-fi film (like 2001 complex) about superheroes? Romantic comedy about superheroes? That shit would be neat.
But again, Marvel may not do well at that, but they do better than DC in my experience. I'd love to see them try to adapt Watchmen again - Snyder's work on it wasn't half bad, but it could have been way better, and it definitely doesn't feel like something that would be just another superhero movie.
