If you loved 2LDK, try Forbidden Siren
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 Yukihiko Tsutsumi, and they sit in Horror / Thriller territory. If that's the register that drew you to 2LDK, the second film will land in a comparable space — through a different lens.
What Forbidden Siren is
Island dusk darkness falls with siren wails. A writer and his children settle into a remote home. Typical of Japanese horror from this era.
