My review echoes many other reviews posted here. There seems to be tale of the two dramas: first 10 episodes – intriguing, full of suspense, last 6 episode – rush and incoherent. The writers of the drama were too ambitious trying to create this huge balloon of excitement but couldn’t find a logical ending to close out the drama. The drama kept introducing many subplots and hoping for a big bang ending, but fell miserably flat at the end.

Acting was decent and average by Korean drama standard. There was OST music to the show. It has a lot of cast members in this show, probably too many to keep a consistent drama in 16 episodes. Once the big mystery is revealed, there is really no rewatch value.
