IT'S THE BEST HISTORICAL DRAMA I'VE SEEN (apart from Mr. QUEEN). It basically have everything, action, comedy, mystery, romance, etc. Also usually most of the kdrama's are about romance and romance only, but a plus point in this drama is that it's focuses really less on romance (not gonna say that their are really little romantic scenes specially after what happened in ep 13 ;)) and if you are really into detective stories then THIS is the story you definitely HAVE to watch. I don't know why the international audience has given this a really low rating, specially when it's doing great in Korea. Trust me when you start watching it, you won't be able to wait without watching the next episodes. Since i'm watching it while onging, yes I'm honestly SUFFERING here while waiting for the mext few episodes. IT'S DEFINITELY WORTH YOUR TIME AND YOU WON'T BE DISAPPOINTED
