This drama is extremely overrated. It's boring. From the premise, it seems original, but its just a generic k-drama romance full of cliches. The main girl is extremely immature and I find the age gap quite worrying. I did not find her too annoying as some people have said, she could be the kind of girl found in high school (still though her immaturity is exaggerated). It is the relationship between her character and the Goblin I disliked- it just didn't work. The romance does not feel real or believable. It feels like a father and daughter, but we are supposed to believe they are in love. It seemed like I would especially enjoy it because of the historical/fantasy aspects, which are genres I love, but these are only very small parts of the drama. Although I did expect these to be only small parts, I didn't enjoy the rest of the drama anyway. I found myself wanting to skip lots or sometimes felt like I was falling asleep. The plot skips ahead often and feels a bit all over the place, as if the writers didn't really know what they were doing. I constantly found myself frustrated and bored with the story. In saying that I loved the parts involving the Grim Reaper, and his relationship with the Goblin and Sunny, and when the fantasy/historical elements did appear I enjoyed them. The acting was also very good. However, overall I did not enjoy this drama and would not recommend it unless you like watching generic, boring romances with poor writing (or watch it and skip all of the main romance- lmao).
