Hmmm...I saw it with my son, I give it 2.375 stars out of five. I had a lot of problems with the story, not that it was weak (it was), rather that is was a lot like one of those inane Tom Clancy films where everything comes together just so and "good" vanquishes "evil" in the last 20 minutes. I hate crap like that.

As far as the CG, yes, it's very, very well done, certainly the best CG ever done for a mass market - but I have seen much better stuff elsewhere.

The 3d didn't matter to me - I don't have much in the way of stereo vision.
