The first couple of episodes pull you in, lots of action, intrigues and hint of romance. Then the politics hits you and many many uninteresting side characters, no loyalty to anyone, you never know who is with who. then you start to loose interest but still the main story keeps you addicted so you don't want to drop it. Basically I just FF the boring details and kept watching the parts I wanted. Still I hardly missed out on anything of the main story. Ji Chang Wook is amazing, Yoona is ok, nothing special, but the main villain vamp is just too good. You hate her for all the horrible things she does, yet you pity and feel sorry for her at the same time. What really annoyed me was the camera work, it was so shaky, literally making me dizzy at times. overall: Revenge revenge revenge. Don't expect it to be like healer, then you are ok. Its addictive and the story keeps you interested but it has lots of boring details.
