It was a cool movie. Lots of action and suspense. Although, a couple parts went on a bit longer than I thought they should have. It was pretty neat though. I didn't really like the ending. It was kind of anti-climatic and left it open for another movie. Then again, I'm not quite sure if I understood the ending completely yet. I'll have to go and see it again before I can make a decision.
Go see it in a theater with DTS or some other digital sound though! There is alot of audio information in the movie and the typical non-DTS systems wouldn't do it justice.
