I enjoyed the show, the 3D and IMAX was a real treat. The movie was somewhat predictable but very entertaining. I think I would actually pay to see it again, the visuals were that amazing.
The IMAX showing tend to sell out so buy your tickets on line. Also go early to get a good seat, the higher up you sit in an IMAX theaters the warming it gets. Don't make the mistake I did and sit behind a bunch of kids, they wouldn't shut up and continually kick the back of your chair.
