Goblin was the first K-drama I ever watched. And I think it is the best drama so far, hands down. If you haven't watched it, you probably should...like now! For you question why you should watch it? Here are my reasons : If we talk about casting- though I'm new to this, I do Google a lot- I don't think their couldn't be any better then this. Gong Yoo did an amazing job. I watched his movie 'Train to Busan' and one could say it hands down that he is an amazing actor, who knows how to do his job. And God his smile....Killer!!! I loved the 19 year old, over enthusiastic Ji Eun Tak who was portrayed by Kim Go Eun. The way we get to see how her character grew throughout the series was a treat. I love Lee Dong Wook as the Grim Reaper. I probably have a crush on the character and the way Lee Dong Wook showed his emotions in it, was amazing. I totally get it why he wanted this character so much. Sunny was my favorite. She was strong and I'm probably never going to see a chicken shop owner the same way. Yoo In Na, changed that for all of us. Duk-Hwa played by Yook Sung Jae was so cute and such an 'rich heir' The story line was perfect in it's own. The fact that it was a fantasy drama, it lives up the name with romance, comedy and mystery. 'The lady in red', 'The king', 'How Duk-Hwa knew stuffs' there are questions that will make sure you stick by the TV screen. And then there is the 'Bromance' The fling between Goblin & Grim Reaper will make you love them so hard. They are funny and cheesy and you are going to love every second of it. The scene where they walk together from the tunnel and the music going on the background, I laughed so hard. Goblin and his bride - Eun Tak is second in the cute couple. They're cuteness will make you cheeks hurt. The story between Sunny and Grim Reaper is a little sad compared to the other. But the beginning was full of fluff and sweet stuffs. Each and every song in this drama is perfect with the story. They will stuck in your head for days and you will be forced to play them over and over again. I'm doing this my self - while re-watching the show for the second time. Especially loved 'Winter is coming' it is just a wonderful piece to listen too. In short.. The songs were perfect. The cast was perfect. The story was incredible. And everything about it ...will make you fall in love with it. So if you are one of those people out there, who haven't seen it yet, I would like to tell you....WATCH IT.
