Sound, visual effects, etc. So my point stands. You even said it was basically only built for theaters. So if you don't have some big time sound system and an amazing TV, does the movie really end up that great?
I think something should just BE GREAT no matter where you watch it for it to be considered great. And with this movie, that's all people ever talked about. It's always "Oh man I had fun in theaters with that one!" etc.
Of course it's just my opinion but just effects with nothing else shouldn't be the only grab for a movie.
