If you let yourself get immersed in the fantasy of it all, it is an absolutely great movie. if you are just there for the visuals, you will not be disappointed. We viewed the I-Max 3D and it was a really fun experience. The future world using today's weapons and technology, makes a great counterpoint to the lush and gorgeous visuals of the natural world being invaded. This film is fun as is and has great moral theme. It requires another viewing to appreciate the finer items missed on the first time. Highly suggest that the 3D version be the one you see.
