I saw the regular 3D version, as Imax was sold out. My grandson told me it was an IMust Imax see. He was right. Took the wife to the Imax version and was once again amazed at the effects. I go to movies to be entertained and taken away.. the people that comment on the story line seem to miss that it is a love story and the other political, war story complainers seem to have their own political agenda, It's a story as old as time..just ask the native americans..
