Black makes use of many genres. Fantasy, with the popular for 2017 grim repear theme, crime, another 2017 popular theme for the k drama, romance, dark, mystery and comedy. The story itself is interesting and the atmosphere is good enough to create that dark twisted feeling. However, there were some things that just didn't work for me. First, the humour was so so and kind of odd in this story. Secondly, the ending. Actually, this one ruined the whole series for me. It was kind of cheesy and not well made at all. So, 6 out of 10.
