Have to agree with fortunesfool on this, the whole thing was too disjointed and forced to reach the heights of TDK. Although TDK had a lot going on within it, I thought it more or less hung together whereas TDKR just didn't cohere. I get that this is a film about a guy dressed as a bat beating up vigilantes with a nuke but when the film gets this serious about its themes and politics I expect more coherency. It felt more to me like it was trying to be epic, rather than actually succeeding.
The Joker's scheme in TDK was implausible, but at least fit with the idea of the character as a very smart, powerful anarchist-type. The central threat in this was suitably fitting for a final film but Nolan's twisted the plot in knots trying to justify everything that happens. Sending every cop into the sewers, waiting 5 months before the endgame, the bad guys not immediately mowing down all the police at the end, the kangaroo court scenes, Bane's exit... the action, as others have said, was awesome, and the whole thing WAS beautifully shot. And Hardy and Hathaway were excellent in their roles. Bane in particular is an awesome villain, but underused. But there were too many moments that made me go 'Huh?" to put it on a par with TDK.
