My wife and I first saw this movie at a non-IMAX 3-D theater and were blown away by it. But since we had also experienced IMAX at Grand Canyon several years ago, we decided to see if there was a difference we could see when comparing normal 3-D and IMAX 3-D. In a word: YES! The IMAX version of this film will pin you back in your seat and never let you up until the credits start rolling nearly 3 hours later. The movie is a visual revelation, an ingenious use of technology to entertain, and breathtaking overall. That having been said, the story is infantile and insulting to the intelligence. So ignore that and bask in a movie experience unlike anything you have ever witnessed.
