I really don't think so because there was plenty of verbal explaining/exposition which pretty much tells you that they were condensing to begin with. More running time wouldn't have helped that.
What they needed to do was not so much cut or add huge elements as they needed to just alter/refine some of the existing exposition. There are certain lines of dialogue/exposition that, slightly tweaked, would have made for a tighter, less messy film. There are also certain lines that just didn’t need to be included, and that added nothing to the movie, but only served to diffuse character motivations. Things like Bane being excommunicated from the League of Shadows, for instance. Its never dealt with, and it muddies Bane’s character motivations. Obviously it doesn't matter that he was excommunicated, because here he is leading them. If you're not going to explore the idea of Bane being kicked out, and Talia's feelings on all that, and how it all intersects, why even bother to include it?
Bottom line, though, is that the film needed another 15-20 minutes for the existing elements to breathe and for a few character interactions, namely Bruce/Selina, Bane/Talia and Bruce/Alfred to be developed a little better and more gradually.
And to have Foley's role axed entirely.
From what a friend has told me, there's about 10-15 minutes that were cut, largely involving Foley's subplot, but no major additions to the core characters/storylines.
Anyone have any idea why this is the only Batman incarnation that DOESN'T visit his parents grave to at least pay respects
The obvious answer is that Chris Nolan obviously doesn’t care about such things. Although he gave us a slightly forced dramatic scene of Alfred weeping at the graves...maybe that was supposed to be his nod to the whole idea of paying respects. Dunno. It would have worked even better if we'd seen Bruce make a trip to his parents graves at some point, but ah well.
