Having had to purchase this series on DVD as not available to stream in UK I am very disappointed. I had read so many good reviews for this series. The plot was all over the place. I am a fan of Lee Joon-Gi and he is a remarkable actor. However he 'overacted' the vampire character. Lee Yu-Bi was miscast in this role and I was not at all empathetic to her character. However, Lee Soo-Hyuk performance was graceful and subtle as the evil vampire (and no, I'm really not a fan of him) compared to Lee Joon-Gi staggering around and making growling noises and strange facial expressions when playing the vampire.
Obviously some people have really loved this series but not me.
Sorry to all the Lee Joon-Gi fans who may read this.
