Query: IMAX: Grand Canyon Adventure: River at Risk [3D] [Blu-ray]

Provides an adequate demonstration of the 3D feature on the new TV, but only during certain scenes. The narration is riddled with extremely one sided points of view that the Sierra Club would tolerate, but I hope the rest of us understand it to be pure propaganda. Not a total waste of money, but when we finish showing clips to the friends who want to see what 3D TV looks like: we'll be happy to part with the disc.
