From what I've read around the web, this dorama didn't meet with a big success. I think the main reason is that it attracted the lovers of vampire stories but it didn't deal with vampirism in the traditional sense of the word. It defeated its own object.

On the other hand, for someone like me who is only mildly interested in vampires and the whole sarg-sleeping, cross-shunning, blood-sucking process, this drama was a lot more enjoyable than I had expected.

I liked the way the issue was approached, presenting the vampires as a decadent, declining, arrogant race who watches the humans with a mixture of desire and deep distaste, boarding on disgust.
It makes it all the more touching when the cards are turned on the table and the one who thought himself superior is treated with contempt for his being different, a "monster".

I confess at being invariably deeply affected by the issue "difference", and how people treat those who don't conform to the norm, either for their skin colour, their beliefs or lack thereof, their behaviour, their look. There are a couple of scenes in this dorama which are still vivid in my memory because they were intensely moving. They made me think once again of how cruel people can be when they ignore and how easy it is to be judged abnormal.

So, although the acting is far from stellar and the plot at times inconsistent, I do believe this show deserves more attention than what it got.
