I talked my wife - no SciFi fan - into going. I don't know which of us liked it more. It was probably me, since I'm going to see it again, but she really enjoyed it also.
The 3D on IMAX was spectacular, the special effects absolutely amazing, the acting right on, and the story a good SciFi plot.
The story did remind me a little of "Battlefield Earth," except we are the Psychlos. That was the only downer. It brought to mind all the useless wars since Korea we've been involved in and how much damage we've done.
