I don't like Vampire stories, but Ok Taec Yeon is such a superior actor that he's always worth watching. PLus he had the backup of two of the funniest supporting actors, Go Gyu Pil and Yoon Byung Hee. There had to be some redeeming moments, vampires or not.
And there were, at the beginning. I've never considered Oh Taec Yeon to be eye candy (just awesome talent), but as he ages and loses some of his teenage sort of gangliness, he's getting quite handsome. He certainly was a gorgeous vampire. FRom the start, though, I didn't care much for the female lead, Won Ji An. Her character was remote, cold, and vapid. I see this in a lot of K-kramas with strong male leads; the female lead is passive, retiring and uninteresting, and I always wonder what on earth the ML sees in her. I wonder if this is cultural: are submissive, fade-into-the-woodwork females necessary to show off the ML? Sure, there are exceptions, but it's the case more often than not. It really made the story unconvincing, especially since Yoon So Hee had a lot more spirit.
The story lost its way somewhere along, and the plot became convoluted while being badly explained and poorly written. The ending was dreadful, it dragged on far too long and was missing any resolution that could have been satisfying. Rather than ending, it became a lame set-up for a second season.
I do have to give a shout out to Baek Seo Hoo, who embodied the evilness and general gorgeousness that I like in a vampire.
Overall, a waste of a brilliant (mostly) cast. My rating is mostly for the cast, with one exception. As for the rest, give it a miss.
