I have to address something that people are pointing out as a flaw; the age gap. I'm going to start by saying that I'm not typically a fan of age gap romances at all, but I feel like there was a purpose in Goblin for the ages and the writers did a great job with their relationship development. They didn't do anything illegal in terms of intimacy while she was 19 - they had one peck when she tried pulling out the sword. They didn't kiss again until she was 20 and they didn't go further than that until she was 29 (if we go off of implication). Yes, when she was 19, Kim Shin admitted that she was his first love, but why is that inappropriate when she would age and he wouldn't? You have to remember that he's essentially stuck at the same physical age and his loved ones all age around him. And if she's fated to be his true love, he will love her at any age. From young to old. In addition to that, the love he feels for her isn't just about romance. Plus, the reason she was 9, 19, and 29 is because of the whole '9' thing in the show, so she couldn't be slightly older or younger than 19 at the age they met. I think I would have had problem with the age gap if they kissed properly (or went further) while she was still a minor, but they didn't because this series is about their fated true love and how they'll always meet. It's a beautiful story of their sad love and life. Age isn't really in the equation.

Story: I loved the entire story. It kept my attention so that I was never bored - despite the episodes being long. The writing was amazing most of the time. I laughed, smiled, squealed, cried, and even got scared by that asshole evil soul who shall not be named. Plus, I loved the fantasy and supernatural theme of the show. It had all the right ingredients to make me fall in love with the drama: romance, fantasy, supernatural, comedy, angst, found family and bromance. The development between Wang Yeo and Kim Shin honestly brought me to tears. Ugh. Anyway, the last four episodes kind of brought down the rating for me a little because everyone was taking turns dying or leaving. But, it does make sense for the show. All the characters were great too, there wasn't a single one I hated.

Acting/Cast: Incredible acting from the entire cast. Although I love Gong Yoo and he played his role perfectly, I feel like he would have been better suited for the role 5 years beforehand.

Music: Perfect.

Rewatch value: If I have time, I might rewatch this.

Overall: I highly recommend watching this if you haven't yet. It really is such a good drama.
