With the popularity of english movies and series like Twilight and Vampire Diaries, I wasn't expecting much with the storyline but seeing as this was Ahn Jae Hyeon's first time to take on a lead role, I was kind of rooting for him. Upon watching the first episode, I wanted to drop the series all together, Gu Hye Seon's acting was annoying and it made me wonder how she was so much better before. The storyline could have worked if the actors were able to deliver them to the audience. Story: It was refreshing to see vampirism as a form of virus. I would say Ji Sang's drive to continue being a doctor despite his vampirism was commendable. However, I kind of liked it better when he was actually doing doctor operations and stuff rather than roaming aimlessly in the hospital. The pinch of romance was okay too what with the dangers lurking just around Ji Sang, he needed something to ground him. Acting: Ugh, I don't know if I should say sorry for saying this but seriously the acting made me cringe and ask myself why I was watching this drama at all. Ahn Jae Hyeon and Gu Hye Seon had NO chemistry together which is so frustrating. Ji Jin Hee was the only one that could act but even his acting couldn't save this wreck of a drama. Rewatch Value: NO. Just no, I just want to move on.
