Totally agree with you on 3D, djblack1313. It was cool when I saw My Bloody Valentine in 3D, but damn, not every freaking movie has to be released this way. Also, the letter was kinda tough to understand at times (what the feck is "strobing"?), but I think what he was saying towards the end is that instead of focusing on a fixed point in space with a 2D movie (just focusing on the theater screen), 3D effects force our eyes to switch from the 2D screen (background) to a raised/projected image (foreground) at a rate that's so constant and rapid that it can be mentally exhausting. It's like if you hold your hand out in front of you and look at that, then look at the wall behind it, then back at your hand, back and forth while both things are also moving (this is what I took him to be saying, though I could be wrong). Personally, I'd like to see more William Castle effects in theaters than a cavalcade of 3D movies.
