A masterpiece of cinematography. The lush under water scenes, crunching of the lava rocks under the boy's feet, the drip of water from the dingy hospital's wall, the muted colors.... I could just go on and on. I made my film student son watch this and we had discussions about the tech aspects of this film. Very interesting. He was very impressed. Don't expect this to be your typical "horror/mystery" genre. It is as if you float thru the movie, absorbing the experience.
