3D TVs are a scam, definitely. Too small! Me and my dad are the only ones in the family who really like the best 3D movies, IMAX HD 3D only please. Please fill our entire field of peripheral vision, top to bottom and side to side. We never get headaches from it and we love it when it's a great movie.

On the other hand, my mom has no ability to perceive stereoscopic vision, because she tends to pay attention consciously to only one eye at a time. The same tendency affects one of my sisters, and both of my daughters. And they all suffer from frequent migraines (although a migraine for them has never been directly caused by watching a 3D movie.) So for a fair chunk of the population, 3D is unfortunately useless.

I think Avatar and the Harry Potter 3D movies are worth watching in 3D, but very little else. And reprocessing 2D movies for 3D is a scam, they're never good enough to bother with. The fully-immersive experience is the key here. The content has to be spectacular enough! When and if George Lucas releases 3D versions of the classic Star Wars movies, I know they will be worth seeing. There's no way he will tolerate a crappy job of that.

I want more and better 3D, but I think the only way to do it at home is with VR goggles. But so far, worthwhile content is rare. But doing it on a TV is foolish.
