I couldn't believe the reality of the 3D affects in this movie. Some images appeared to be right in front of your face and depth perception was almost uncanny in that you felt as though you were falling over the edge of a cliff in the scene. At times I could feel the "vertigo" from the heighths. The story line was well done, although not original. . However, my only complaint would be that the film makers used the opportunity to make political comments aimed primarily at the US and previous political figures. I'm tired of the "apologies" and the guilt trips we are supposed to have for being Americans. We are and always have been a beacon to the world and God forbid we should ever be ashamed of that.
