This series was.... BRILLIANT. It had action, comedy, romance. It out you in your feelings, EVERYTHING. The actors did such a great job here. They all brought their own personality to the characters and gave them life. Hell even the bad guys you will love. Lee Seung Gi did such a great in his role. I don't know how a man can deliver such mean lines and still make you swoon. The Devil King was amazing too and just hilarious.
The soundtrack was amazing. If you didn't play When I Saw You hoping to see that sexy monkey standing behind you, you didn't watch this series right!!!! Rewatch value? Hell to the yes.

Overall this was such a cool show that kept you entertained and engrossed in the story. You didn't get bored once. Episode 20 was such a great closure to this series. It made me feel better after what they did to me in 19.
