This movie was excellent, one of the best movies I've seen in a while. I found that even though the movie is 2hrs and 40min, the time went by quickly. There were very few areas (two maybe) where I felt the movie needed to pick up the pace, and those moments did not last long before more action was "thrown" in your face. In IMAX 3D, the action is literally "in your face." It was great! Debris seems to almost hit you. I thought some scenes were a little blurry around the edges, or when there was a lot of fast movement. However, I think it's because the IMAX screen is so big- kind of like sitting 12 inches in front of a 55" LCD tv. :) I'd go see this movie again, and I will most likely buy it when it comes out on Blu-ray.
