Blood started with a very, very good base plot. It is very unique—I watched Blood in the first place because it's a medical drama and on top of that, the protagonist, who's a surgeon, is a vampire! It's a total paradox, which made it quite interesting. How can a vampire possible operate on a patient without harming him/her? Atisan mainly solved the problem for me, but after it stopped working, ALL SCENES INVOLVING OPERATIONS WERE GONE and it seems that it started going away from the medical genre. All hospital scenes were talk, talk, talk (or patients being given shots or being taken blood from). Nonetheless, I continued watching because I wanted to know how the problems will end but IT STILL FAILED MY EXPECTATIONS—especially the ending. The ending left too many unanswered questions with the most important being "Were the patients in Ward 21A cured?" Because of too much focus on Ji Sang and his death wish, all the patients were ignored (or no one knows if they were really cured). The next important thing was "Who rescued Yoo Ri Ta at the end?" (Watch the ending if you haven't yet to know what I'm talking about and WHY I used "who".) As for the acting, I'm actually more impressed with the acting of the antagonists especially Director Lee Jae Wook. He gave so much into his work that I was so pissed off by his character (which is a good thing). On the other hand, Min Ga Yeon became one of my favorite characters (the other one being Joo Hyun Woo because his life's work is my frustration in life, seriously I want to be like him) because I totally didn't expect her real nature. Her seemingly innocent character was so well-done that I truly loved her as the series went on. Let's move on to the music. Unfortunately, music from Blood wasn't memorable to me at all. Music is there to sway our hearts, but it failed its job. Even if I mentioned a lot of fail parts I still give the drama a high rewatch value because of the following reasons: nice startup story, Joo Hyun Woo, and LUUVY!!! LUUVY is the biggest reason I look forward to scenes at Park Ji Sang's house aside from Joo Hyun Woo. I love this robot so much. As for those who are planning to watch blood, STILL, WATCH IT. Even if you're feeling a bit disappointed right now. The trick is, don't have high expectations (like I did). I'm not forcing you, though. After all it's a unique piece of entertainment that exists just for entertaining you. Don't get too serious over it.
