I haven't been to a movie in 3D since I was a kid and saw a 3-D-ified version of Murders in the Rue Morgue (I think it was this one). The technology sure has come a long way since then.
I don't even know how the story was. I think it was pretty good, though, but the immersive quality of watching in an IMAX and in 3D was just phenomenal. Highly recommended.
