This, deserve a 10/10 from me. I am a fan of medical forensic drama. And, I love OCN's dramas. So, this drama is basically a combination of both my favorites. I've watched a few dramas with this genre, either from Asian, or US. Vampire Prosecutor, Virus, Body of Proof, CSI:NY, Brain, Surgeon Bong Dal Hee. But this one is, simply amazing. This drama maybe has the highest score among all the drama I've reviewed. Story: the story basically had no defined plot at early episodes. It just contains separated cases each episodes. But later a plot was built and unexpectedly made a twist (which was a pleasant surprise). The case about rare disease is REALLY interesting. The cases are not using a really "smart" or "tricky" strategy, but rather, it's interesting because the case was actually solved by solving the victim's or perpetrator's disease. And of course, I could take notes learning about rare disease (which, I really interested into). And to add the plus point, it contains a bit romance (and a sweet one :)) Acting/Cast: I must admit, dr. Han is really charming, in his own way. He's smart, but quirky at the same time (and different from other main characters from other medical drama I've watched). Ryu Deok Hwan is absolutely worth praising. The interaction between the team is also hilarious and warm, which I really enjoy. All the cast did a fantastic job building the character, so, 10/10. Music: actually, there's not much music. I do believe, OST bombardment is not for medical drama, because atmosphere is not really the main point. But to be honest, this drama had better OST than other medical drama I've watched. Rewatch Value: I'm not the type who would rewatch the dramas I've watched. But if I put myself on other's shoes, I definitely would want to rewatch this, someday in the future. Overall: Even though it lacks in music, but it doesn't matter for me. This drama still scored 10/10. The acting is terrific, nothing to complaint. It blown me away after I watched the first episodes and got me addicted (to the extent that I neglected all my currently watching dramas beside this one). This drama successfully rises to the top 5 of my all-time favorite dramas, and I am now excited to watch the second season. Apparently this drama had similar format with other dramas, but with its uniqueness, I would highly recommend this drama for those whose fond of medical dramas (and those who doesn't mind bloody and autopsy scenes).
