I got interested in this movie after watching a clip of Kim Gwang Il getting kidnapped on YouTube. The clip was amazing. Filled with action. My heart rate rised as he was pulled out of the car. Seeing his facial expressions. His great acting. I knew, I needed to watch the movie. Sitting down by my computer I was soo exited. The first few minutes of the movie was great. I loved watching the murder. How Lee Jong Suk killed the role as a serial killer. But as the movie continued, it got more and more boring. Nothing happened. Lee Jong Suk didn't get the screen time he deserved. They included far too many side tracks instead of following the head plot. They followed too many persons, which led to confusion, and the main detective were supposed to be a cool detective, who doesn't care a sh*** about the law. He only became a boring cop trying to catch a serial killer and failing way too many times. The perfect movie should have followed the serial killer and the detective only. The exiting part is the thills and finding out why the serial killer acts as he does and how the detective fail to catch him or end up catching him. I don't recommend using 2 hours of your day watching this movie. It has nothing to give you. However Lee Jung Suk did amazing and I recommend watching all the edits of Kim Gwang Il on YT.
