First of alll, the iMax experience wasn't 'real' for me. I grew up in Northern California, and have experienced the real imax dome...this was just a screen similar to a movie theatre. The Jim Carrey voice-over sounded immature and unsoothing to the ears. The film itself is only 40 minutes, but that's kind of a good thing because your eyes begin to hurt from the 3-D visuals after half an hour(even through the glasses).
