I'm really late to the party on this one, but...I liked it. Just liked it, though, nothing more and nothing less. For me, this is another example of aggressive stupidity in summer spectacle, a'la Prometheus (but perhaps reduced); The Dark Knight Rises is big, loud, and not too terribly concerned with making a ton of sense. In that regard it's something of a failure for me, since Nolan is a far better storyteller than TDKR suggests through its sloppiness (seen in its repetitiousness, both within and without the confines of its structure) and utter dopiness. I do appreciate that Nolan seems to be reveling in the comic book origins of his world and his characters, and there's great joy in how he personally plays around with all of the fun toys Batman has at his disposal while introducing us to Kyle and Bane and generally making his world feel like the sort of world where these tropes and concepts and ideas can exist.
But I wish it was all in service to something tighter. This thing plays very, very loose. Also: sorry, Bane sounds fucking ludicrous. I think you can enjoy it on that level, but there's nothing intimidating about the off-the-stage theatricality of Hardy's voice work here. It's enormously fun, but ill-fitting considering who Bane is and what he represents, which turns out to be fuck all since he's not really the heavy here-- a move that turns out to be the film's biggest mistake.
I did love the hell out of Bale here, much more than I have in the other movies, and I honestly wanted so, so much more of him and Hathaway bantering and playing off of one another. They put on some of the film's best moments, but more than that I think the ending would have really benefited from some more meat on their story's bones.
This might sound a lot like the opinion of someone who hated it. I didn't hate it. It's a fine film. Just not the film it should have been.
