I don’t like nor dislike 3D, personally. However, I totally forget I’m watching 3D after about 10 minutes and I ask myself: why am I paying extra money for this??
^This^ I sometimes like 3D in the theater, but my brain flattens the image before long, and I have to keep switching to polarized sunglasses (to make it properly 2D, in IMAX, at least) for a little while to make the effect obvious again when I put the 3D glasses back on, but it never lasts. At best, if the 3D isn’t really shitty post converted cardboard cut out looking stuff, I still kind of appreciate subtle depth throughout, like roundness of faces… but that’s about it.
