If you loved Raining Blood, try Zombie Ass: Toilet of the Dead
A bridge between a film you've already seen and one most people haven't. 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 Noboru Iguchi, and they sit in Comedy / Horror territory. If that's the register that drew you to Raining Blood, the second film will land in a comparable space — through a different lens.
What Zombie Ass: Toilet of the Dead is
Mountain road. Summer. A discarded hair scrunchie. Megumi, haunted by her sister's death, joins some seniors on a trip. They stumble on a backwoods experiment gone wrong: zombies born of human waste. Iguchi's splatter-comedy dares you to look away.
