I generally enjoyed this show, the music and story were great and the actors all had great chemistry. Although the FL seemed to fall flat on occasion compared to her male counterpart. He really worked his arse off to keep the scenes alive when this happened. I assume she is a little emotionally stunted due to her childhood and the things she sees, which is probably the reason the actor comes across as flat in some scenes?

The comedy from Ma Wang (Cha Seung Won) is just great, especially when he bounces off of Son Oh Gong (Lee Seung Gi). Their whole love/hate/respect relationship is gold.

Overall it was a great watch as kdramas go; action, romance, comedy, supernatural, etc. - There's a lot of genres this show falls under! I would recommend giving the show a watch and it's definitely one I would rewatch, in fact, I already have.
