Y'see, I hate 3D movies because I already wear glasses and, yes, wearing two pairs of glasses for the length of a movie gives me a headache.

(And no, I'm not going to get contact lenses just to watch a film.)

But your friend? Augh. I hate when people claim to hate things without trying them first. Try it, hate it, then complain. Don't skip the first step, it makes you look like an asshat.
