I just got back from it. I enjoyed it but not without reservations.
HERE BE SPOILERS
On the one hand it was bloated and pretentious but given the epic scale of the thing, I'm willing to overlook that. The scene where Bane set his plan in motion (with the bridges being demolished and the football field being torn asunder) and pretty much the entirety of the third act contained the kind of spectacle that you don't often see in a cinema. That's definitely a good thing.
The first act did drag but there was at least a point to it. I thought the film did a good job of stressing the immensity of the weight being placed on Bruce Wayne's shoulders (mainly by Bruce Wayne). I liked the way Bane and Selina Kyle were introduced and thought both characters meshed well with the universe Nolan had created over the course of the two previous films. I'd feared the worst with Selina Kyle/Catwoman and was pleasantly surprised by how strong a character she was.
Perhaps my biggest criticisms of the film were the leaps in logic it asked the viewer to blindly accept and the contrivances it expected the viewer to simply ignore. Just how many times can Batman swoop in at the last second to save someone from certain death before we start to question how he knew those people were in danger, and where those people were at any given time? How did Wayne get back to Gotham City so quickly and without being seen? Why did he take the time to shave? How did he track down Selina Kyle so effortlessly? Isn't she supposed to be elusive? Why was Lucius Fox left to live when Bane (or even Talia) could have so easily killed him and saved themselves so much potential grief? These things could have been explained away by a tighter script. It's disappointing that they weren't.
There were little things that bugged me here and there like the film's anti-socialist message being presented as a simplistic and axiomatic truth, eliminating any and all shades of grey; the silly flying "Bat" that looked like something out of GI Joe; and that ghastly fucking shot of Bruce Wayne nodding to Alfred at the end (that shot's one saving grace is that I don't believe it was intended to categorically illustrate that Batman survived the nuclear blast; I think it was tempered with ambiguity and represented what Alfred WANTED to see, but not necessarily what was there).
So yeah, it was not without faults, but I definitely enjoyed it. While I wouldn't rate it as highly as The Dark Knight (or Batman Begins for that matter), I think it was a worthy finale to the best comic book trilogy ever made. And given how abso-fucking-lutely spectacular it was in parts, it wouldn't even register as a disappointment necessarily. But to unconditionally praise it (as I'm sure many, many people will do) would be to delude oneself in the glare of rampant fanboy-ism.
