saw in 3d, but it seemed to be that annoying retrofitted 3d so i put my 3d-to-2d glasses on. would've gone for a 2d screening but there wasnt any
personally, its just not worth me getting a headache and going cross-eyed all the time unless its an avatar or life of pi quality shot-in-3d film.
so really want to see in 2d without the 3d glasses based light loss. come on local cinema get your act together!
