I have not seen any of the NEW 3D movies, but last week we were at Disney World and saw the 3D shows by Disney. They are cartoon shows and the effects are amassing. Characters come right in front of you and you can't resist trying to touch them. My Daughter who has taken her kids to the latest 3D movies said they were no where even close to what you see at Disney World. In one scene a flying bugs gets in your face and you can fell the breeze from its wings.
I have heard that a number of people can not handle the 3D effect and get headaches or nauseated. I personally will past on this NEW technology.
