The issue for me with 3D is that even though it’s immersive with its stereoscopic illusion, your brain is performing an unnatural optical function, converging your eyes where you’re not focusing them, and there’s a feeling in your head that it’s hard. There’s literally a feeling in your head that’s a little bit different than what you’re used to feeling, and so I find myself unable to forget that I’m watching a movie. And for me that’s a bit of a barrier.
