I saw the film yesterday. I was enjoying it on several levels. The plot, the characters, the cinematography, the insight into modern Korean culture. Then, in the last quarter of the film there were several bloody, graphic horrifying murders. At least of the murders was a great defect in the plot. These murders and an unnecessary sex scene
ruined the film for me. I do not recommend this film despite some of its positive aspects. You can spend the time in more enjoyable activities and you will not have terrible images etched in your mind.
