Ok Mr. Cameron, I get it! Humans rob and pillage Mother Gaia. Ferngully rises again in wide screen 3D and motion capture. I give the story line a C.
But what 3D it is. We have had the technology of stereoscopic polarized lenses for a while now, but nothing previous to this production took their time with it, and used it to push cinematographic grandeur. Most films just threw things from the screen at you. An A+ for cinematography and attention to detail.
Acting went from weak to over the top with the fun exception of Michelle Rodriguez. How many actors can make you laugh just through the proper delivery of the line, "Oops" after she pours rounds into the ship of her antagonist.
