The real problem, for me, with a lot of these female superhero movies, is that they don't have likeable male characters in them. If you want to attract men, you need male characters in these kind of films that they can identify with. Often, men in these films (villains, boyfriends, etc...) are kind of wimpy. The Dark Knight Rises and the Amazing Spider-Man both had very likeable and strong female characters (Catwoman and Gwen Stacy). Female superhero movies need to find that same kind of balance, but in reverse, so that male audiences can identify with the male characters.
