This sums it up I watched it on my iPad firstwhile I was on a long drive and was thoroughly unimpressed. But I rewatched with a buddy of mine which some drinks and on his huge high def tv with a nice sound system and I was blown away.If you didn't see it in imax 3d Atmos or whatever, then yea.
Those specactular movies are a must-see-in-theatres type of film. I loved it but would never watch it on a plane.
