It was very good. The plot was old, but interesting with a new twist. The CG was fantastic and the sound was good. I grew up knowing imax as the screen that would engulf the audience at museums. This time it was not the case. The glasses made me feel skeavy as they were oily and the lens's dirty. Also they were too tight for my normal sized head which caused a headache. The screen was nothing special and I felt that some parts of the movie where blurry. I credit my frustration more to the theater itself than the actual movie. I will return after the holiday rush to view in digital 3D or 2D so I can compare. I will be purchasing the Blue Ray so I can view it on my HD home theater as well. I would have rated the movie a 5 of 5 otherwise.
