If you are looking for a mystery movie that answers everything neatly, this is NOT the film for you. Even after the movie is finished, you leave just as confused as you were the entire time. For those who can handle that, you should really watch this movie. It was really cool to see Jang Keun Suk play such a twisted character; his acting was spectacular and he speaks English! The movie was really intriguing and had you thinking you knew who did it, only to switch your opinion again and again. I recommend this to anyone! If you're not satisfied with not knowing the answer, check out the Wikipedia article AFTER you watch the movie. The case was reopened after the movie and culprit was found from DNA testing, 14 years after the murder occurred.
