I was informed this was a terrifying horror film. It is actually a long drawn-out drama with a gross ending. There is a bit of shock value, but I don't understand how the main character, Aoyama, finds all this out. He sees the man with the missing fingers in her house, and then it shows he was in his own house the whole scene. Where did the man go? And the man in the wheelchair. First he had a head, then he lost it, and now he has a head again. I'm not a doctor, but that doesn't sound normal.
I will give this movie a C- for wasting my time. I could have watched other movies for Horror Week.
