Highly overrated. Can't believe it got +40% ratings in Korea. I can only justify its success on Ji Hyun's return to tv acting, which caused hype. The special effects and cinematography were great though.
Saw the rating here and had to comment: This drama is in now way as good as its current rating shows (second overall). It was solid, 7-8/10, although, like most k-dramas, it dragged on some parts. As long as you don't go in expecting the masterpiece the rating here suggests, it will be enjoyable.
