Most Disturbing Movie Ever?

i think this is, i saw irreversible, ichi the killer, i stand alone, three extremes, oldboy, sympathy for mr vengance/lady vengance, last house on the left, i spit on your grave, pink flamingos, a clockwork orange, eraserhead, mulholland dr., battle royale, basketball diaries, etc. (and im not even 18 yet, but thats not the point) anyway, i thought that this movie was way more disturbing than anything else i ever saw. does anyone agree with me?
