One of the main reasons why I watch this drama is because of the original story of the Monkey King. This drama does have a lot of extra elements but it does stay loyal to the original story. It's also very funny especially Wang Ma moments. The relationship between Wang Ma and Son is really genuine; even though they seem to be against each other they are always looking out for another drama. I really their bromance over the main romance between ML and FL. Maybe, because I saw many good actresses in the past, I found Sam Jang [Oh Yeon Seo] acting skills to be lacking particularly her facial expression which didn't fit some of the scenes. Otherwise, she did a fair job. I like the zombie girl [Lee Se Young] better as she really plays the role of innocent girl and evil concurrently to its potential. All other characters were very unique as well like Pk and Yoon Dae Shik which made it more fun to fun. This drama also seems to play heaven as the "bad guy" because of love but then again the heaven is meant to carry out destinies to balance the force between peoples' free will and the universe. Aso, not the typically happy ending but it was understandable because Son and Wanf seem be more expressive of one another at the end and Wang also found his son. Wang and Son are one of the best duos in K-drama. I really feel like there could be a season two for this as there were a lot of unanswered questions or reunions.
