I was not sold on it first. Initially the movies where too gimmiky and they always tried to make it more 3d than it should be ( Ie: throwing stuff at you etc.. )
I do however now enjoy 3d more as movies are now just filmed like normal but in 3d. No special 3d treatment in most cases.
This I think makes it better. The movie is the same but now with some depth. I like it like it is now.
