^Yeah, but wouldn't badly written characters of either sex turn off viewers of either sex? Why even make it a gender issue if you're actually talking about the quality of character writing?
The Dark Knight Rises is a film with strong performances from all of the male and female characters, that encourages repeat viewings. All of the characters are strong and well written. The Amazing Spider-Man also had a strong male/female dynamic. For the life of me, I cannot think of a single female supehero movie where this is the case. Supergirl? Halle Berry's Catwoman? Tomb Raider? Electra? Men are often dumbed down in these films. If that isn't sexism, I don't know what is.
