I feel the hole 3D movie craze is just another way to get money from the consumers. They want you to buy there 3D glasses to watch there 3D movies at the theater, than they ask for them back when you leave. Than they want you to buy special 3D TVs so you can watch there 3D DVD's. I even heard that some directors don't like filming in 3D because it limits the angles of there shots.
I don't know maybe this hole 3D thing will turn out for the better.
