Red&Blue 3D Glasses DO work, but they're horrible, because you can't see the real colors of the screen, because of Red and Blue color.
Cyan, however, (the typical ones the assistances give you when watching a 3D Movie), are great, because...well it's cyan xD
I don't like 3D though, because first, they make me dizzy, second, it ruins the quality of the movie, and third, the glasses are too big for me so I have to push them up every 5 seconds, which is annoying as crap.
