I wouldn't forgive those problems just because it was a comic-book movie. I think it's the fault of the filmmakers and not because it's a "comic-book movie."
And, not aiming at ISM, but in general the sterotype comic book movie in the public eye always seems to see this. The eyes roll and its another guy in his underwear and the biggest hurdle is Hollywood going with those types - but then when Dark Knight comes along and blows everyone away, they're all shocked. Well, the material is there and the potential - it's just that no one steped up and moved beyond "Comic book movies."
Anyway...
