Well, didn't see this one coming. I had just finished my first drama with So Ji Sub (Master's Sun) and was searching for another one of the same genre with him starring as well. Came across this one, and although an action/serious drama was everything I didn't want, I still gave it a try because, well, it's So Ji Sub. And, oh, thank God I did. The story developed perfectly along the 20 episodes, although in my opinion there are way too many flashbacks and a few fillers. I loved how the flashbacks were displayed and how the quality was pretty different from the present time action. I don't have many things to point out except I still have my doubts concerning some hidden cameras displayed in questionable flashbacks. Other than that, this drama got all my attention and was the best company for the last days of my holidays. I had seen Ghost's poster before, but it never got my curiousity because it had Lee Yeon Hee and, well, I really don't like her acting from what I've seen of her. This drama didn't convince me otherwise. She's too... 1 dimensional. In my opinion (although I'm no acting expert at all), she still has a long way to go. On the other hand, there's So Ji Sub and his eternal amused look with his sympathetic frown (it does make sense if you know what I'm talking about). Since I'm considerably new to So Ji Sub and thus I don't know him exactly well, I have to recognize he did a great job, but there's another actor that took the spotlight. Absolutely loved Kwak Do Won's acting. I saw him on Good Doctor, but his acting there is far from as good as it is in Ghost. He perfectly portrayed the frustrated and mad detective. I must agree with the awards given to the main cast. So, although I feel like taking a point off the acting, I think of both So Ji Sub and Kwak Do Won and I just can't. Lee Yeon Hee, I want to see more of your expressions. Being a pretty face isn't everything... I took extra attention to the music ever since Phantom of the Opera's theme started playing out of nowhere. It caught me by surprise and it did scare my at first, but then whenever it played again I would just laugh. But that music isn't everything. Overall, the OST was pretty good. 10 points for P.O's sudden "Burn burn out out" at the end of one of the first episodes. This drama exceeded all my expectations. Lately I've been into a melodrama, 16-episodes drama mood but this actually changed and surprised me. I recommend it to anyone who likes a bit of action, police-related series and really handsome boys. (y)
