Surreal. Never read any of Junji Ito's works. I've only seen his artworks through social media. I don't like horror much, but let's see how long I can keep up with this one.
The animation is so smooth, I wonder if they did rotoscoping for the movements. The black and white really brings out the body horror. It really captures the Junji Ito vibe perfectly.
One of the things I was most curious about with this series was the animation style they were choosing to use. Hiroshi Nagahama used rotoscoping to make Flowers of Evil, but that doesn't seem to be the case here. The mouth movements would have been better - they actually look pretty rough in spots here. Motion capture or vtuber tech maybe?
It seems very faithful to source material. They're paying proper homage to Junji Ito's art with the strongly contrasting black and white visuals. A full color adaptation would have dulled the horror of the spiral.
