Where do I start with this drama? [Side note: I love revenge dramas, one of my favorite categories. I happen to watch this and Incarnation of Money at the same time. In my opinion, Incarnation of Money surpassed this drama in not only plot-wise but also pace-wise. I recommend if you enjoyed this drama, watch Incarnation of Money next.] To begin with, the soundtrack was amazing. I ended up downloading many of the songs played in the drama up until the end, such as there were some awkward songs that didn't go with some scenes. The end of the drama also seemed rushed because some scenes were recorded with a very shaky effect, like a documentary and there were way too many scenes with unnecessary closeups. Overall, I really enjoyed this drama but I didn't love it. This drama did not have me on the edge of my seat until the very end. It was a continuos plot of "I'll kill you...later" up until the end. I didn't at all like Min Hong Ki, especially toward the end. It was as if he was giving police badges to people like lollipops. It become so annoying how many people at the end were undercover cops and how many were shot through the head. One aspect that I actually hated about this drama was the damn reporter that had the hots for Ji Hyeong Min. WTF, bitch?! His girlfriend of many years, who he was about to propose was murdered, and then this woman pops up and tries at every given moment to flirt with him and make dates. HE JUST LOST HIS BELOVED! IT TAKES TIME TO MOVE ON!!!! Moving on, I love the concept of knives and swords because it makes fighting fair than rather with a gun but in this drama, seriously, why didn't any of the characters carry guns?! Would have solved so many issues, but then the drama would have been short. The actors, great overall performance by them. My favorite was the actor that played Safari; he was such a wild card, I loved his character to the end. Because this was a drama noir, the romance given was ok. This drama didn't need romance to make it watchable. I liked how it was well-balanced with the drama, action, and romance. Why I rated this drama a 9 was because the last 2 episodes felt rushed. Overall, as stated, I enjoyed this drama and the acting but it also ended with an ambiguous ending, so that was annoying.
