Go see it in IMAX if you can, the REAL 3D version shows compression of the 3d effects and some depth is lost. The IMAX was the best 3d I have ever seen. The also showed previews of upcoming 3d movies...the new shrek movie looks really funny. They also showed a preview of the real life NASA mission to repair the HUBBLE telescope....the real live images from space with the space shuttle in orbit was truly astounding in depth and quality.
Loved the trailer on the Hubble repair! Beautiful shots...
