I understand that some people do have problems with 3D; but I wonder if the problem is with the technology, the way that the technology is implemented (insufficient brightness), if it's possible psychosomatic, or a combination of the three.
Since 3D cinema pretty clearly empirically does "work" for most reasonable definitions of the word "work", arguments that it theoretically cannot work are obviously evidence of either bad theory or pointless misuses of language, or both.
It seems to me to be more of trying to find an excuse to justify why they don't like it and to try to convince others not to like it. (Hell, it roped in Ebert, didn't it?) Personally, I love 3D. I don't get the headaches or nausea, even with red/blue 3D. 3D does work
