I enjoyed watching this movie. This dark, twist bad-cop good-cop plot. Story line is not outstanding, there were some nice turn-ups I have to say, but overall this movie did not made me curious what will happened next. If you like movies about dirty cops go ahead and watch it, you will like it. But if like this kind of movies and you watched a lot of them, this one will not surprised you in the good way. Acting was great, mine eyes seek only for Joo Won of course ^^ but Uhm Tae Woong stole this movie from him. He was the shining star, actually whole story we see thought his eyes. There is nice chemistry between them, thought mutual goal characters can overcome their differences and finish what their started, fighting for justice. Even if truth isn't always what they want it to be. Music good, whole instrumental gave me nice vibe thought the story. Great fit with the scenes. Movie worth watching because of the actors, nice action movie with cool lines and even few funny moments.
