As much as I hate the recent spate of 3D movies, I don't think it has anything to do with the technology, but more about how poorly it is applied. I say this because Avatar, at least for me, was simply mind-blowing; it was easily the most immersive film I've ever watched, but mainly because the 3D was done tastefully, subtly, and with care. You can give me as much hand-waving sudo-science to try to convince me I'm no…
Nothing like an un-biased view of how "3D" will never work from a guy who has built his career off of making sound-systems.
The only fundamental difference is one of wavelength.
