The one other major gripe I had was with Bane's plan. In Batman Begins, Ras explains the evolution in the League's approach to collapsing cities. What begins with fire and plague rats slowly develops into corrupt commerce and dirty politics. In Batman Begins, the League manages to infiltrate every level of Gotham's infrastructure.
In TDKR, with all previous attempts proving ineffective, it seems like Bane's new plan is to radicalize Gotham's people, manipulating them into tearing the city down themselves. This is a really fascinating idea. Poisoning Gotham's citizens with the power of "belief" rather than just fear gas.
... but then you just find out the real plan is to nuke them.
One other missed opportunity: The identity of the trigger man! They could've done something really cool with that plot device. Once Batman returns to Gotham, Bane could've told the city that Bruce Wayne, the most elite of elites, was the man with the trigger. He'd have turned the whole city against its savior. I get that "my own ideas" =/= fair criticism, but I'd have loved moments like that. Instead, the third act feels rushed and sloppy as it fights to contain its half-dozen plot threads. Don't get me wrong -- it's still a pretty robust blockbuster... but it's one of a few films that I constantly find myself going back and forth with.
