I suggest people watch a few different films of his close to each other. Maybe a night like Dead or Alive, Ichi the Killer, The Happiness of the Katikuris, and Visitor Q. Maybe even Gozu, Audition, Izo, One Missed Call, and Deadly Outlaw: Rekka. There are plenty others to toss in like The Bird People in China or Big Bang Love, Juvenile A that can help you form an opinion on his work too.
