My problem with the Nolan Batman's, and I include Dark Knight, is that Nolan seems to hold them to a higher standard. He seems to be under the impression that he's making some profound, high art thrillers, when he's really just making a boring superhero movie. The smarter he tries to make them, the dumber they seem. Why does the energy device have a huge 'countdown to destruction' on it? It's not actually a bomb, its an energy device! His dialogue is awful too - really ponderous and on the nose. I lost count of the amount of times the film ground to a halt so someone could deliver a monologue.
At least Joss Whedon had no pretensions that he was making something other than a glorious, fun, superhero movie.
