Visually stunning! The landscapes were so convincing, my friend wanted to wait through all the credits to see where it was filmed! The story was very moving and well told. My major criticism was the lack of character development of the 'skypeople'. So much thought was put into the rest of the movie, it seems they got tired, took the easy way out and grabbed a corporate greed/military smash-everything-in-sight stereotype. That was disappointing.
