While watching this movie, I got so absorbed in it I was unaware of my surroundings. Just when I thought I lost my interest in revenge stories, this movie wakes it up again. It also explore how society deals with its kids, specially at that difficult age. The story is simple. A teacher's daughter gets killed, and the culprit are her students. She teaches them a vicious lesson, one they might never get up from, and they will certainly not forget. Ignorance is when you think you know it all. Thats why teenagers tend to be ignorant and look down on adult. I liked that she managed to show them who's boss. But in doing so, you feel that she lost her humanity. She didn't teach them out of care, she hates them but just doesn't want that crime to be forgotten. The children themselves, their thirst for attention blinds them from the crimes they do. They have no conscience at all. To be look up to as cool, they take it on the weaker, like cowards. It reminds me of an essay I read some time before where it says that children are more dangerous than adult, because they have no morality. They can do the worst of crimes and not realize its atrocity. Basically when they do those kind of crimes, they should be punished like adult and face the consequences. The acting from Matsu Takako was top notch. I specially liked Kaoru Fujiwara;s acting her. The cast is generally great. Okada Masaki's character was plain annoying, because he was meant to be lol. I loved LOVED the direction here. The use of flashbacks, the skip from one flashback to another (as if watching an old family video) during conversations and monologues, the lighting and effects, the colours of them moving, was used effectively and perfectly. I think its what made the movie stand out and what absorbed me in that movie. The music used is no exception, setting the mood perfectly. As a psychological thriller, it carries the task perfectly without being a burden to watch. You're never thinking "I just want to know the ending of it". It might not be to everyone's taste, but Its definitely worth the watch ;)
