I assumed, most people found this kind of drama boring, not interesting, scary, confusing. But, not for me. I took virology class, and this drama helped me to reviewed my lessons, as well as comparing it with what I learned (errr, sorry for sounded like a freak).. Anyway, I started watching first, because it's from OCN. I admire OCN's drama. I mean, it's not mainstream. I really love Vampire Prosecutor (and now dying to watch the 3rd season), and finally I found another drama. And I was interested when I watch its trailer, and so, here I am. Story: as I said before, it's unique. The virus idea is not-so-original though, since I've watched "L Change The World" which made me fell in love pretty hard. And since, the virus used is kinda look a like, I kinda disappointed actually. But I decided to focus at the story line. And indeed, the story line is interesting. Not only medical, but it involved political issues (which I assumed, also happens in reality as well). Not only that, I spotted a classic scientist's issue - ethics. I'm aware, that ethics always been a sensitive, but important issues. I'm glad that the scriptwriter actually included ethics issues in it - may take that as a moral of this drama. The details also pretty great and realistically made. Acting: Uhm Ki Joon, no need to be questioned. His acting is terrific, he portrays smart and persistent Lee Myeong Hyeon really well. As for Hyun Woo, even though he only appeared in the first half of the drama, he left a pretty deep impression on his acting for me. Yubin, I'm kinda surprised to see her here. But her acting is pretty good (and I kinda startled to see that she........ *I'm not posting spoilers here. LOL*). Other casts are also great. Music: nothing notably, really. There are barely any music throughout this dramas. Only opening and closing sequence (same song), and barely noticed instruments as insert songs. Nothing remarkable. Rewatch Value: basically because I didn't rewatch my dramas. But in my opinion people wouldn't watch this show twice. Overall, this drama is basically a medical, thriller, a bit gore (a few scenes containing bloods). In my personal opinion, this is a good way to test your knowledge about virus. The story is FAR from romance (moreover comedy). It's serious, dark, unexpected, but pretty realistic. But I do recommend this for those who interested in medical drama.
