“Thank you and fuck you brother”

Kunihiko (Masaya Katō) wants to avenge the boss who was killed when a feud between two yakuza families spilled out of a nightclub. It started small, with a young gangster tormenting the customers in a rival family's club until his body turned up. Takashi Miike lets the killing pile up past all proportion, and the camera keeps looking.
