If you choose to see it, then IMAX 3D is recommended. The 3D effect, and beautifully rendered computer assisted and generated scenes and textures are lovely to see. (The physics are sacrificed in favor of visual impact.)
Do not expect any awe-inspiring science fiction that asks and answers "what if" questions--this is best left to the classic science fiction books, from which many ideas are taken in a tastes-good smorgasboard of concepts. The ideas are sci-fi lite; it's fast food for the mind, with no deep nourishment.
The action moves along at a good pace, with predictable character development and story arc.
This is a decent comfort movie where you won't have to think, and you can just sit back and enjoy the 3D.
