Marvel is more about escapism while DC is focusing realism. This way we get he best of both worlds. And lets not forget that the comics that these movies come from do focus on a lot of real life situations as well. If you've read TDKR then you'd understand what this film is representing. There is realism all in the comics. Maybe not as much as these films, but its definitely in there. There's gotta be a good balance or else no one can relate to the story which is the whole purpose of cinema.
