To many separate components need to improve.
-
Hardware. Right now, 3D TV’s require special glasses, or they only support a single viewer in a very narrow viewing range.
-
Content. Movies made for 3D with depth effects are better than old shows remastered to have “pop out” effects. I saw Pacific Rim in Imax 3D and it was amazing. I also saw Nightmare Before Christmas remastered for 3 and it was fucking terrible.
-
Infrastructure. Cable/Service providers need to provide services capable of streaming 3D movies consistently with solid performance.
-
User acceptance. To me, the market is still prioritizing picture, sound, and frame rate over 3D effects. People just don’t care for it right now.

It would just take your daily home power usage to do a single 2hr movie.
