The concept of the story was great, the execution was terrible.

Either the Goblin needed to be much younger or Eun Tak needed to be much older. The Goblin was a 39 year old man before his transformation, the FL Eun Tak is a 19 year old HIGH SCHOOL STUDENT whose parents died when she was young. She was living with neglectful, abusive family members, she comes off as vulnerable and naïve. She is in no way mature in looks or acts. It is hard to buy that a 939 worldly Goblin/man is going to fall in love with a girl who acts like an entitled toddler. The fact that he does is creepy. I have zero issues with age gaps in general, but the age gap is glaring since Eun Tak is written to be so immature and spends most of her time dressed in a school uniform. The whole time I watched there was no chemistry between the two, which I am glad for but also it is supposed to be a romantic fantasy drama, at least cast it so we don't feel skeeved out every time the leads are on screen together.

What I saw of the Reaper and Sunny was great. Deok Wha was enjoyable and should have more of a story line. The bromance is great and should have been more developed.
