If you loved St. John's Wort, try Blood
A bridge between a film you've already seen and one most people haven't. Blood has roughly 3.6× fewer votes than St. John's Wort — 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 Ten Shimoyama, and they both carry the dread mood tag, and they sit in Horror territory. If that's the register that drew you to St. John's Wort, the second film will land in a comparable space — through a different lens.
What Blood is
Mansion dusk. A scream. A blood-slicked blade. Detective Hoshino arrives at the Rozmberk estate, where a vampiric seductress and an Edo-era swordsman appear locked in a deadly dance. Soon Hoshino, too, falls prey to Miyako's thrall. A lurid, minor key in the J-horror cycle.
