Seriously that was my reaction to several scenes in this movie. At the end, I felt as if my IQ levels have dropped drastically. That's how dumb this film was.
Now where to begin? Let's start with the plot of the movie. Whoever wrote the script was definitely high on something.
In the first place, you cannot have all your characters being phenomenally stupid and/or taking several decisions which are highly dangerous to their lives. But that is what every character in this film does, right from the start till the very end.
If the main character had an iota of self-preservation instinct, she would not have gone alone (OK she takes a cameraman with her) to interview a crazed serial-killer in an unknown location. And if she had refused then this movie would never have been made. But Koji Shirashi wanted to make this movie, so that is how it starts. And then it goes downhill in a spectacular fashion.
The lead character keeps provoking and challenging the crazed lunatic serial killer and pushing him over the edge. Basically it is shown as if she is trying to talk some sense in him. And she is supposed to be a trained reporter.
Then two extremely unlikely characters enter the fray and the absurdity of the plot plummets further by several notches. The movie then disintegrates in an orgy of sex and violence, which is so surrealistic that I wondered if I had slept off and was experiencing a strange dream. Everybody kills each other as if it is no big deal at all. It is extremely disgusting and voyeuristic, not to mention unrealistic.
The ending was good. That is the only positive thing that I can say about the film. One star for that.
