STORY: Well, I really love genre's such as fantasy, supernatural with romance in it and I did liked this drama and it was a good rendition of the Journey to the West. Well, the story was great from the beginning but honestly I hated the ending so much, it needs a season 2 or atleast a special episode to have answers to the question, I did not like that the ending was hanging!!!! I was crying T_T!
CAST: The cast was a plus to me because I love Lee Seung Gi ever since My girlfriend is a Gumiho and Gu Family Book and it was the first time for me to see this Oh Yeon Soo acting and she did really well and plus she's pretty too! The chemistry was great as well (you can see it in their kissing scene), also I liked the supporting characters especially Ma Wang, I think he was the one with the best character development in this show.
MUSIC: Well, I really love their songs and everytime I remember Hwayugi the songs keeps on replaying on my head over and over again, I even had all of the song on my phone! hahahha whenever I go on a trip it was one of my go to songs LOL!
REWATCH VALUE: Yeah, for me I would rewatch this just because I love the interaction of Ma Wang and Son Oh Gong!! HAHA (sometimes I even root for the BROMANCE rather than their leading ladies, HAHAHAHA - sorry I have this thing for yaoi lol even in Goblin too the bromance is strong on that one as well)
OVERALL: 9/10 - I was a bit conflicted on what overall score to give, I would have rated it higher had it had a better ending than that... it would have been lower if not for Ma Wang and Oh Gong LOL
