I think the pacing was off. One simple way it could have been fixed: At the outset, Wayne )and Bats) have been out of the public eye for eight years. I think his brief reappearance should have happened within the first moments of the film (Nolan needs to learn something about pacing a film) and fight with Bane should have occurred within 20 minutes of the opening logos. Thus his subsequent imprisonment and return would have more power. As is, it weighed down the already-much-too-busy final act.
