After "playing" with 3D for the last couple of months, I agree that it is not a mature technology. Charging the glasses, wearing the glasses, eye strain, ghosting, etc. I have only watched one full length feature film in 3D, Tron Legacy, which does not have some of the more extreme effects. Still, at the end my eyes were too tired to watch even 2D.
Then some rather odd behavior on sports shows when telephoto lens are used. Compression of perspective is common on telephoto lens. But when a player on the side line looks about as tall as a player mid field, something is way wrong.
