Unlike some heavy going costume dramas this is easy to follow with it's simple straight forward plot. a jester who looks like the king fills in for him and institutes some changes. If you can accept the premise that he can look and sound so much alike then it's an enjoyable watch. Lee Byung Hun is a commanding actor. Liked the ending not being depressing. The setting is nice - looks like lost of other Kdrama palace sets. Han Jyo Hoo is pretty as the queen.
