I admit that I'm pretty late to the game (2 years late actually) but I've been holding off Goblin for a while and since I'm currently watching Touch Your Heart, I decided to watch Goblin while waiting for the remaining episodes to air. Anyhow! I loved watching this drama. The characters were so genuine, sincere, and wholesome. I'm a huge fan of Lee DongWook as well as Yoo In Na :) The OST is absolutely amazing I'm pretty sure everyone who hasn't watched this drama have heard of "Beautiful" by Crush at least once before. The cinematography never fails to keep me in awe. The panning and perfectly well filmed shots are so captivating and makes the whole drama aesthetic and beautiful. The plot goes a little fast at times and they don't explain certain things but the acting and casting covers up for the small flaws. I highly suggest this drama and to those who are hesitating to watch, I'm telling you: watch. this. drama. now.
Also, I'm pretty sure you already know that this drama isn't exactly your typical romcom romance drama. It's pretty darn sad. I cry at least three times in one episode so prepare some tissues.
