For the first 8 episodes I thought I would definitely give this drama a 10. The acting was great, the shots and editing was fantastic and IU's wardrobe was simply stunning. It was a joy to watch. At the same time, the characters seemed interesting, the ghost stories got me involved and both the present and the past storylines were equally enganging which doesn't happen often. However, close to the end the drama was getting worse and worse and it was mainly due to the script as the actors themselves were definitely top notch. The plot became all over the place, their problem resolutions were totally unsatisfiying and for the last few episodes it wasn't even interesting to watch anymore. The glaring problems with the script became evident and even the beautiful sites couldn't hide them anymore (20+ hours of just stunning aesthetics with no meaning is definitely too much). The only well developed character was that of Jang Man Wol, even Gu Chan Sung was underdeveloped and existed mainly as a plot device to JMW's character. It was also advertised as a rom com but I definitely did not get the feeling that it was. It was quite funny and unlike many others I don't have complains that the main couple did not have chemistry, they did it was just completely different. More of a mature romance / deep friendship than cute head over heels romance. For me the drama could have ended on episode 15 and nothing would have changed much as for the storyline itself. There was no resolutions or questions left to be answered in the last episode, just unnecessary scenes that couldnt even decide whether it was to be sad or hopeful or what. I was left unsatisfied with the development and the direction it has taken. The only reason why the score is so high is that production value and acting was through the roof.
