3D is not going to be here forever. People are already tiring of it at the movies, and until they design a glasses-free 3D TV, there will be a limit to how many people will buy 3D TVs. In fact, sales of TVs are way down? Why? In my opinion, it's because those who have nice LCD sets don't feel the need to "upgrade" to 3D sets. Where's the content anyway?
I am so anti-3D, that even though I'm a huge Lord of the Rings fan, I may not watch The Hobbit in 3D, opting to catch the film at the 2D screenings. To me it doesn't add to the experience, it interferes with it. Whenever they design scenes to "highlight" the 3D experience, I cringe; you know the arrow directly at the screen, or anything, really, thrown at the screen; pathetic. When 3D is used like color, to merely make the experience better, then I'll jump on the bandwagon; until then, I will not be watching 3D anything.
