Badass japanese movie by Takashi Miike.
Features the most deranged dellusional psycho-killer-in-a-crappy-costume-who-kills-those-who-make-him-cry-and-cums-his-pant-in-the-process, and Kakihara, a stylish and dangerous extreme masochist yakuza leader.
This awesome flick is mostly known for its graphic and inventive torure scenes and bizzare characters.
Hated by people with no sense of humour who are probably Christian and big fans of Hollywood bullshit.
"Yeah dude, show me the part where the guys face slides down the wall."
