I've decided I'm against 'em. There are too many flaws in the experience which distract me from the actual movie. Here's an ordered list:

1. The glasses make the movie too dark. It's like watching with sunglasses on. I can't see shit. Perhaps this could be fixed by making the projection brighter.
2. Glare. The glasses are cheap, so the surface is not perfectly flat. This makes shiny white patches occur all around the periphery. Then there's the additional glare caused by the damn exit signs on both sides of the screen. I understand the importance of safety, but do the exit signs have to light up brighter than the movie screen? Shouldn't they be just a little less bright?
3. The ticket costs more. Boo.
4. At its best, the 3-D effect can be pretty dazzling. However, it's just as often all out of whack, like when there's a lot of quick movement on the screen and your eyes can't quite focus. In between these high and low points, there's the bulk of the movie, where the effect isn't dazzling or messed up, and you don't pay any attention to it at all.

So effect-wise, the lows cancel out the highs, and grievances 1 through 3 bring the net impact into the negative. Damn this newfangled technology. </andy rooney
