*NO SPOILERS*
Definitely the best storyline of the 3 movies.
Much better than I was expecting, and if you told me it was better than the Dark Knight (which I thought tried to shove way too much in 2 1/2 hours, and was a little hokey in parts) I wouldn't argue with you.
But man, Bane was just unreal. The most terrifying villain in any Batman film ever. He is just brutal. He may not be as lovable as the Joker, but I loved seeing Bane on screen, and his dialogue is so much easier to understand than the prologue.
Hathaway was also great.
One of the best things for TDKR for me was we finally had a Batman film where you really cared about what happens to Batman. Too many of the prior Batman films had him constantly overshadowed by the villains he faced. In TDK, as great as it was, I never got an emotional connection with Batman. Even when Rachel died, he was bummed, but I was hoping for a little more (I'm sure I'm in the minority on this).
But in TDKR, you really feel for Batman/Bruce and you finally see a super hero film where you can think "Oh my god, he is ed, the city is ed, and this can't end well." Bale definitely gave the best Batman performance to date, and it's not even close with this film.
You can argue TDK has the higher highs (mostly involving the Joker), but TDKR flies by with superb pacing, and honestly, from start to finish I think it was the more consistent film in terms of its plot/storyline.
I'll be anxious to see what everyone else thinks, especially of Bane, but god damn, so much better than I was expecting.
And if you can see it in IMAX, do so, this film is definitely the "biggest' Batman film in terms of scope and ambition.
