The show started off promisingly - it kept to the 1-hour mark, the storytelling was zippy, and there was the right balance of humour and mystery. But as the show went on, it became less enjoyable, due to the amount of airtime devoted to certain aspects of the stories and the flawed portrayal of the villains. Cha Seung Won does such a good job - he's proven his comedic chops in Greatest Love. He still brings them to the table in this show, though not as much as in Greatest Love. He also shows that he is a very good dramatic actor. It's good to see that Lee Seung Gi is trying something different in this show, where his character is a lot darker and mysterious. I'm really pleased that Go Ara is getting good roles after she did an excellent job on Answer Me 1994. On a whole, still an enjoyable show.
