My second time to see it and my heart still races during the flying scenes. The 3D makes it feel like you are "in" the movie. Climbing the floating mountains was amazing. Discovering the local animals and plants with Jake was clever and fun.
I really liked the extra scenes added to the orginal. The new details add complexity... you get to see inside the closed school w/ bullet holes, an analogy created by the "american indian" bison hunting, burning of the dozers, steamier love scene and death of the warrior.
Was it just me or did they add all the bugs and flies to this version?
I took my parents who thought 3D was too gimmicky to go to the first release. They loved it.
