3DTV has always been too much work for the consumer. You have to pay the big ticket price of getting a 3DTV. Then you've got to get a pair of glasses for each viewer. What if you're one pair short? Plans ruined? Then you've got to get the 3D version of the movie. What movies do you even consider watching in 3D? Personally, I can only think of Avatar, Gravity, and maybe Dr. Strange.
