Normally I'm not drawn to a fantasy genre, but this had such good reviews, and I'm a fan of actress Jung So Min so I thought I would give it a few episodes. I was caught up in the story from the first episode. The strength of this drama are the visuals, from costumes, to sets, to the actors, to the CGI magical effects, it has been done with great quality and attention to detail. I also enjoy period pieces that mix some modern-day touches in with the historical. The production transports you into the fictitious Daeho and makes you feel this is a real place. The ending surprised me, that is all I will say about it. However, it did end in a way to set up Season 2 and I'm thrilled there will be a second season. It is well worth the 20 episodes.
