This movie was 100% predictable, because I've seen it before. It was Dances With Wolves/Last Samurai meets Ferngully: The Last Rainforest.
The really sad part was the soundtrack. James Horner recycled his old tunes from Glory and Willow. It's really annoying to be watching a movie for the first time, and get distracted with "no where have I heard that music before..."
The 3D experience was great, as an experience, but having already seen UP in 3D earlier this year, it still paled. All in all, it was a great popcorn flick, but popcorn flicks don't last 3 hours long.
