Okay so the hardest thing to say about this drama is, unless it had Ahn Jae-Hyeon and Gu Hye-Sun in it I probably would NOT have watched it past the first 5 episodes. I pretty much think it was completely wasted on their talents and the storyline was lacking. Did I appreciate the fact the writer made the vampires come from a virus instead of mythology - yes it was creative but that’s probably where the creativity stops. To see evil get more evil and people just dropping dead for the sake of it is a wasted story. No creativity in it.
Rewatch value = I wouldn’t waste my 20 hrs of time on it thank you. Once was more than enough.
