I think I may be having a PTSD reaction to this video. I've been feeling sick to my stomach for hours, and my roommates are asking whether I've got a fever, because my eyes are all glassy and my face is flushed. Evidently the film used extremely low-frequency sound to create a state of disorientation and unease in the audience, causing a huge number of walk-outs (Newsweek magazine stated that this was the "most walked-out-of movie of the year").
Y'know what the most distressing part is, I think? The point, about 5 minutes in, where you see that someone has walked into the passageway, and sees the rape in progress...and then just turns around and walks away.
I feel sick.
