I'm not usually a fan of science fiction but I did enjoy this movie, particularly in IMAX3D. It's long, but the story is fast-paced and gripping, and the beauty of it will transport you happily away from the everyday. It has the right combination of action, romance, and good vs. evil and, in spite of the fact that you've read or seen the story before, the presentation makes it fresh and exciting. I would put it on a must-do list, and I would see it this way.
