@serkol this isn't the first time 3D movies have come into fashion but they didn't catch on back then. Maybe it will be different this time but personally, I think 3D is much more of a gimmick than colour tv or cinema.
Personally I don't see the appeal of 3D because after 10 minutes of watching a 3D movie I completely forget about the 3D and just enjoy the film. If anything, when I do notice the 3D it takes me out of the film.
