XD actually means Extremely Deafening. Even with fingers stuffed into my ears, I couldn't stand the volume. A shock of bright images and repeated, rapid movements coming from all directions made me queasy and dizzy. My nervous system felt assaulted. J didn't fare much better. We left.
We returned for a different showing of the movie (Inception), without the extremes. That was better, though both of us closed our eyes during the Big Bad Gun shootings and constant explosions, neither of which were advertised in the movie synopsis. Much of the acting, at least, was fine. But the story seemed silly, and the ending predictable. One teen behind us, after the show was over, joked, "Where am I?"
I enjoy viewing films on the big screen, but it's a highly unpleasant experience to sit through half a dozen excessively loud, boring, or offensive previews, and then watch the violence at which (apparently) much of our culture doesn't bat an eye. And we think this explains, in part, why so many people are losing their hearing while they're still young.
