It's basically Fern Gully the live action remake, starring giant smurf native Americans.

I saw it in 3D when it came out, which would have been more impressive if I hadn't already seen Monsters vs Aliens in 3D.

Novelty 3D in the cinema release aside, there's nothing to recommend this (seeming) 9 hour movie.

Also it has about 3 different points where I went, 'oh that's the end of the film... No, wait, it's still going.' After l thought the movie had reached a conclusion or climax, I thought it again after another 15 or 20 minutes, and then again, and then I think again, for an hour after I first thought the movie was about to end.
