If you loved The Sylvian Experiments, try Toshimaen: Haunted Park
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 Hiroshi Takahashi, and they sit in Horror territory. If that's the register that drew you to The Sylvian Experiments, the second film will land in a comparable space — through a different lens.
What Toshimaen: Haunted Park is
Tokyo, summer. A child's paper balloon. Five friends revisit a shuttered amusement park of their youth, seeking lost innocence. They find only a labyrinth of malevolent spirits, eager to play new games. Takahashi knows J-horror's haunted-location beats.
