I enjoyed this and feel that some commentators have rather missed the point. There is criticism for the inclusion of the evidence of the girl during the first half and also at the behaviour of the wife. In both cases there is absolute clarity and relevance as far as I am concerned but possibly the film is overlong and the feeling that there is nothing happening grows if the story is not fully understood. Even when there is no wham bam action I am always happy to see those strange little Japanese streets and houses and listen to the polite niceties as the tension builds. Worth a watch and the creepy guy is certainly as creepy as they come, also true life events are alluded to and there are echoes of recent terrible tales as this horror unfolds.

The first half is creepy indeed. The neighbor, his garden with overgrown plants and the dead bodies in plastic. But then everything becomes clear that the neighbor turns his victims into obedient zombies with some drugs and nothing is explained further. It's some miraculous drug and it makes them kill for you and be there for you. The bodies in plastic looks really creepy and so is the little town. He formed another family with his new neighbors and the detective shot him when he asked him to shoot his dog so apparently the drug didn't work on him. No explanation as to why or how he achieves all these things.

Good looking movie with an interesting story that unfortunately falls flat because of the totally stupid and irrational behaviour from every single character (main characters, detectives(!) and police) in every single move and decision they make, which is something that drives the movie from beginning to end. One single rational and normal act early in the movie, would've ended it in 10 min.
