If you loved Retribution, try The Guard from Underground
A bridge between a film you've already seen and one most people haven't. The Guard from Underground has roughly 5.8× fewer votes than Retribution — 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 Kiyoshi Kurosawa, and they both carry the dread, paranoid, slow burn mood tags, and they sit in Horror / Thriller territory. If that's the register that drew you to Retribution, the second film will land in a comparable space — through a different lens.
What The Guard from Underground is
October midnight, fluorescent buzz. A broken locker door hangs open like a mouth. A night watchman in a stained yukata finds the receptionist’s head in the shredder then switches sides, blade in hand. Kurosawa’s night-shift nightmare where paranoia outranks paychecks.
