I just saw it, and loved it. My long anticipation seems to have been richly rewarded. It wasn't so much a great action movie as a powerful film with a lot of action. The ending was fantastic.
Christopher Nolan has to get a lot of credit for creating a trilogy in which each film is great in its own right and each builds on the previous; the Dark Knight trilogy never ran out of steam. Also, in closing the series the producers avoided the probability of losing creative momentum and letting an uncapped series run aground. This trilogy sets the bar high for other 'superhero' movies to match, though the Spider-man remake was a great improvement on the films earlier this decade.
