This is truely a cinematic event, especially in 3D, no doubt the best 3D release I've seen to date. The 3D was so natural and that the viewer is not even aware of it after a few minutes, other than it seems like THIS is what movies are supposed to look like. It lacked the flashy look-this-is-3D shots that are prominently featured in most 3D releases, instead using the technology to immerse the viewer in a magical wonderland of nature and the ways and relationships of creatures there.
There is no deep story or complicated plot here though, the simplicity of which is surprising considering the rest of the effort and the sacharine Saturday morning cartoon ending is a little disappointing.
