It was an absolutely great movie, probably the overall best in the past few years. I did think it fell under the main-protagonist's-last-job "heist" genre/story except instead of money/gold being the objective (think Ocean's 11 or The Italian Job), it's your dreams, subconscious, ideas, etc. That said, the movie's execution and the amount of layers each reality had was original and brilliant.
Saw it for a second time, this time in IMAX. The fight scenes were even better on a larger screen, plus the stereo system had everything rumbling, making the whole movie that much more intense. I also liked that the females were written better than in Nolan's Batman films. Can't wait for the Blu-ray too, just wished Nolan did more commentary on his films.
