There comes a time where I deviate from my usual way of watching things. I'm the type of person that either watches an airing show as soon as it comes out or binge watch an already-finished drama as quickly as I can. Unfortunately, I didn't do that this time as I would have liked to. That would bring me to the main part of my review: the fatal flaw. It drags. Yes, the nightmare you all dread, hiding behind your fortress of speedy Japanese classics and 16-episode Korean wonders. I stopped at episode 18 and didn't pick it up for months. It just slowly came to an unbearable halt. It's not like the story wasn't interesting - it just went on. And on. And /on/. When one problem was finished - oh! there's another one. That itself was not well structured. It was like watching reality TV with plot points being dragged out from the darkest depths of cinematic hell and suck in to keep it mildly entertaining. That was a huge blow to what otherwise would be... quite a great drama. Believe it or not, the story was pretty good. Despite the former, I genuinely enjoyed the storyline. I mean, it kept you guessing for one thing --- maybe because of a lack of proper explanation, but well, that's one way to do it. The other fantastic thing was the acting. A fairly star-studded cast graces us with their sublime acting. Kim Jae Joong (who played Kim Kyung Tak) was particularly good (the eyes!). The other minor let-downs might have been the soundtrack. None of the songs honestly piqued my interest enough to remain in my memory, and I remember noticing the songs entering at really strange times. Not fluid at all. More like a tear falls and suddenly you have a random ballad flash in. If it were faded in and out - or even better -had a better composed OST, it would have been nothing to complain about. Overall, I myself enjoyed it. The ending was exceptionally good - I enjoyed that very much. The majority of the drama was set in the past (exactly what I like from a historical drama, if it wasn't obvious) and the medical scenes were realistic, and realistically gory. It wasn't over-the-top (though some might disagree) and yet it still played a strong role as a theme in the drama. If you have a lot of free time, perseverance and like continuous problems in the plot - here's your drama.
