It started out nice. But then... firstly, I would cut the number of episodes down to just 8. And one episode should be 45 minutes long, max. The cinematography was great, Koreans are masters in this stuff. But what in the hell were the dialogues about? I'll tell you: absolutely nothing! I watched the version with Korean audio and English subtitles so MAYBE a lot got lost in the translation? But still... it was painful to watch. It went on and on and on... was it a zombie horror? Teen drama? None. It was like creators couldn't decide.
