only two. the first one was at the sf film fest, and we saw this horrible horrible japanese horror film called "ichi the killer."
recently we went to the sf indie film fest and caught "irreversible," walked out within 30 minutes. basically the film is done memento-style (backwards) about a guy who tries to find the man who raped his girlfriend. there's a 9-minute rape scene, but we didn't even get to that point. the director added what we know as "brown notes" during a crucial and already violent scene, heightening my nausea. here's a clip from a vice mag article:
He added stroboscopic sequences that cause audience members to literally spaz out, and boosted the soundtrack with subliminal infrasound that makes you want to shit your pants without knowing why. “This sound has the same effect on the body that earthquakes have on a city,” boasts Noe. “You can’t hear it, but you can feel it because it goes straight to the pit of your stomach.”

the weird thing is, we hadn't known about it until we got home and did some research on the film. it explained why my boyfriend suddenly felt like he needed to take a shit when we walked out of the theater.
i have a chance to interview the director... still debating...
