If you loved Ichi the Killer, try Gozu
A bridge between a film you've already seen and one most people haven't. Gozu has roughly 4.7× fewer votes than Ichi the Killer — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Takashi Miike, and they both carry the unhinged mood tag, and they sit in Crime / Horror territory. If that's the register that drew you to Ichi the Killer, the second film will land in a comparable space — through a different lens.
What Gozu is
Nagoya. Morning fog. A discarded orange peel. A yakuza lieutenant accidentally offs his boss, then the corpse vanishes. Our man hunts for answers, finding only bizarre characters and stranger situations. Miike's phantasmagoric fever-dream is not for the faint of heart.
