Absolutely heart-wrenching, crime thriller...keeping in mind that this masterpiece was produced in 2003 before the case of the Hwaseong murders had been solved, this emotional rollercoaster of a film depicted with such great acting really has you on the edge of your seat. Whether you know the case well or not before you watch, this movie is gripping from the start to the finish.

The depictions of good cops and bad cops brings a certain degree of realism to the film, with Song Kang Ho's character development and his commitment to the case changing throughout the movie, it shows how at the start he was just focused on getting the job done, but as he becomes more attached to the case he realizes that he doesn't want to just get the job done anymore, he wants to find the right person no matter what it takes. He is already an outstanding, renowned actor in South Korea, and seeing him in his younger years in this older film really shows what incredible talent he has had from the start.

Kim Sang Kyung's character 'the good cop' plays the law-abiding cop who is passionate about the case, coming from Seoul to the very countryside areas of Hwaseong because he is determined to solve these murders and capture the correct criminal too, he is also depicted in an incredible manner. Out of the whole cast you will find yourself relating to this character the most, not only is he compassionate and determined but the frustration and continuous unanswered questions he is faced with will have you on the edge of your seat gunning for him to catch a break on this case.

Overall without too many spoilers, the acting in this film is fantastic, the cinematography shown despite the constant dark settings were filmed beautifully and effectively from the start to the very end of the movie, keeping you interested and engaged throughout it. The plot was developed in an interesting and realistic manner considering it's based off true events. Definitely worth the watch, and a re-watch.
