Really liked this. I like magic, supernatural and special effects although the political background story is unoriginal. In the middle it seemed to have too much "slapstick" comedy interfering with the plot but became more interesting when they allowed the story to develop. Yes there were many plot holes and as usual with these sageuk stories dragged out the ending over three episodes and it is giving nothing away to say everything ended all sweetness and light except for the big villain, however you have to go with the flow I think and just enjoy it as escapist drama if you like this kind of drama. I thought the chemistry of the characters was good and I was especially impressed U-Know acted well and looked good. One I enjoyed and looked forward to watching every evening but would not re-watch after knowing the story.
