Koroshiya Ichi was a delectable romp. Dead or Alive: Hanzaisha was hilarious. Miike is LOL. If you think special effects is sick then you're too easily hypnotised by movies. Yes, movies hypnotise you.

'sick' movies would most likely be those 'banned in America' things, imho. I've never watched them per se, but the idea of watching a parachuter fall into an alligator/crocodile swamp doesn't sound very 'enjoyable'.
