That was a train-wreck of a drama for me... this is coming from me who really likes almost anything 'vampire' in it and I did start the drama and watch it until the very end because of that. I did not like the beginning... it was hard for me to get into the story, then it did get interesting and I somehow got a little attached to it ( that was somewhere near the middle) and I started to like it but then they ruined last few episodes...
Main lead did look vampir-ish and nice, as I remember (I watched it when it was airing) and OST was really good. I think that's what I liked... that robot too was kinda cute. LOL (and one other character too, as I remember... but I don't want to talk about him. :/)
