I dunno, I gotta say the only place I hear the complaining about glasses, headaches and all that jazz is the internet. No one I talked to about this in real life complains about it and each 3D movie I went to see so far was pretty much sold out. (Internet)-People make way too big a deal out of it. Sometimes I can't even tell if I saw a movie in 3D or not months later, that's how natural the glasses and the look feel for me already.

People should have the alternative, of course. At least in the cases of crappy post-production transfer to 3D.
