If you loved Minamata: The Victims and Their World, try Grass Labyrinth
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 Grass Labyrinth is
Alice in Wonderland if sex-positive. A young man chases the origins of a childhood song. He tumbles into a phantasmagoric realm where past and future blur. Terayama's fever dream overflows with carnivalesque imagery.
