It is always surprising when a sequel not only meets, but exceeds the expectation of the audience. I was blown away by this film. I adored 'Batman Begins' and agreed with all those who stated that it breathed new life into a well-worn franchise. I can say with no reservations that I felt this film was just as exceptional, if not slightly better than it's predecessor.
Each and every actor in this film brought their A-game to the field. I was mesmerized by Bale and Ledger equally. My only real point of contention was that Eckhart was given a meaty role, but was not allowed to fully dig in and expose the bare bone. It felt that there was quite a bit of build-up to his fated transformation, but once it happened it seemed as if the screenwriters got bored and wrapped up his arc as quickly as possible.
I highly recommend this film, and for those who can afford the additional cost of the IMAX experience, do so. There are only 4 sequences that utilize the technology, but they are truly worthwhile.
