Loved the 3D and technical aspects of the movie. I was amazed at the number of objects that appeared to be floating between me and the screen, and a movie set at great heights in 3D was incredible. I've parasailed and hot air ballooned and been less height sick. I agree with other reviews - this story has been told and retold dozens of time. It's like a handout for the current "Green" movement. We are too bound to wealth over environmental issues, but everyone is already aware of that also. Still, it doesn't hurt to be reminded.
