It has been ages since I saw a drama which was so addicting. I was watching this drama knowing that it is good but I never expected to be that good. I can honestly say that this drama was one of the best dramas I've seen so far (despite some little things). STORY I really enjoyed the storyline. In the beginning it had many surprising turn overs and it had many unexpected scenes. I was totally hooked on the story. In the late episodes the quality of the storyline fell down a bit. However, I think that writers did an amazing job here. I can't think of any flaws in the story right now, like I can find in other dramas. I think that if you watch this drama you will find out how addicting and GRIPPING this drama is. Seriously!!! I've finished this drama in 2 days! CAST Well, there are some flaws when we speak about the actors and their acting. I think that Kim Yoo Mi (as Lee Jin Sook), Yoon Hyun Min (as Kim Hyeon Soo) and Choi Moo Sung (as Safari) did an amazing job!!! All of them are really talented and I could believe every scene they were in. As for Jung Kyung Ho (as Doctor's Son)....ehm...well, I dont't find him handsome but he is somehow very attractive. He's not really a good actor in my opinion, however, I think, that he fit the role very well. But I don't think that I will watch something with him ever again. As for Lee Jae Yoon (as Ji Hyung Min), he has to work on his acting skills as well. However, I can imagine him as a police officer, which was his character in this drama. He seemed to me a bit like Seeley Booth in 'Bones'. Nam Gyu Ri (as Yoon Soo Min) did a good job as well, however, I found her character really annoying. And finally Son Chang Min (as Min Hong Ki). Currently, I watch ?Glorious Day' and I love him in there. His character and acting is perfect in 'Glorious day'. However, his acting was soooo bad in 'Cruel City'. And I loathed his character as well. OST I loved the OST. When I first heard 'Hurt' by Kim Yong Jin in the 1st episode, I was....so... I can't even explain it. For me, this song is master piece. I can still think of scenes where I heard this song. And I really liked the instrumental soundtrack as well. Overall, well because this story and many unexpected twists and surprising turn overs, the rewatch value won't be so high. I think that this drama was outstanding, despite the bad acting of some the actors.
