-I don't hate "Blood" but I feel like they could have done a much better drama, because the story is interesting, I mean, a vampire who is a doctor, is quite interesting.
-The drama had a good start with everything, but then things got out of place and boring
-About the cast...hm...I'm a fan of Ahn Jae Hyun, to be honest, physically he looks like a vampire, but his acting kind of failed...the same with Gu Hye Seon, I really loved her in "Boys over Flowers" but I don't think this role fit her, but I'm happy that they got married, because they had a great chemistry in the drama and they look cute together.
-The bad ost....
-The disappointing ending! I can't even understand if it was supposed to make me happy. The writer really didn't care about how to make an ending, he was like "Let's not give a shit and put the end like this". I need explanations!!!
-Overall, I can say, this drama was a waste of time. Bye bye my sweet 20 hours...
