This was totally my cup of tea. I love crime shows. If you are looking for romance or comedy, then this is not the drama you are looking for. There are comedic moments that relieve the intensity of the drama, but they are few and far between. This drama gives you a look into what could happen if you get your personal information stolen and it isn’t cute. I think the story was well thought out and there were no inconsistencies. I do think that they used a lot of flash backs, but if you are confused about anything, then it does help explain events. Although they reveal the criminal early on in the drama, it doesn’t take away from the suspense. He is like one of the smartest criminals I have seen in a drama and I was totally happy about it. I get tired of watching stupid “bad guys”. Watching the cyber team try to take him down is very intense and at times I found myself screaming at the monitor. The ending is off the hook!!! So Ji Sub is my favorite actor so you may see this review as biased. LOL I think he did a great job playing Woo Hyun as cold and serious and then playing Gi Young as Woo Hyun with a more passionate attitude. He seemed like a different person to me and I would have seen right through it. Uhm Ki Joon plays Hyun Min, the “bad guy” with perfection. I could sympathize with why he did some of the things he did even though I don’t condone his actions. I totally fell for him. His smirk is just too cute. You should watch him in Scent of a Woman. If you are watching this for Choi Daniel, then don’t waste your time, because he is barely in this drama. He is in the first few episodes and in flash backs. All of the other actors did a great job too. I especially like Kwak Do Won as the Mad Cow and I always love seeing Kwon Hae Hyo. Hae Hyo is totally underrated as an actor. I have seen in tons of dramas as the supporting actor and he is always awesome!!! The music in this drama is off the hook!!! I love the Phantom of the Opera music. I don’t know if I will watch it again since I know what happens, but it is definitely a must see for those of you that like crime dramas (and/or So Ji Sub).
