If you've read the manhwa beforehand (of the same name) get ready to be very disappointed. The weakest point of this drama is possibly the story that forces talented actors to fit typical, spineless roles. If it we're not for Lee Joon Gi and Lee Soo Hyuk I would have given up on this one from sheer frustration.

Certain characters had unlikely changes of heart, the female lead was one of those ditsy types who can't steer her own life and the ending was half-arsed. The drama felt severely dragged for no good reason and one can sense the springing up of another new useless obstacle or twist- they rely on these so much to pull you through the snail pace. Eventually, the show only decides to end once the omnipotent vampire lord decides 'screw it' and is ready to face death head-on.

The drama contradicts itself regarding things like how long it takes for a human to get turned into a vampire and every time the duration is as is convenient to the plot.

The villain was very good though and the alluring vampire plot has been delivered fairly well with enough nitty gritty without too many holes in their 'functionings' so to speak. The second coupling worked quite well and realistically.

The whole concept of this drama is really great and it mostly manages to deliver on that front despite it's shortcomings. It's a recommended watch for me.
