This drama was mediocre, compared to all the crime related dramas I have watched. Every time this drama hit a good climax in each episode, the resolution/ending would undo all the built-up tension and excitement. The crimes lacked good explanations, and were usually resolved with vague interpretations that had no details. The story relied too much on the main character to drive the drama. I felt he was too calm for the events that were going around him, which made things less exciting. I wasn't sure if it was the actor or the role itself. However, throughout the drama, he actually developed a personality and emotions, which made him slightly more interesting. If the writers concentrated more on the developing the side characters, the drama might have been more interesting and the main character would not seem as boring. I did like the uniqueness of the the villains though. They weren't the mainstream villains everyone is used to seeing in Japanese dramas. Everyone was super crazy and twisted by Japanese standards. I thought they were more interesting than the main character. Most of the tension and excitement was due to the music. The choral music was placed at exactly the right moments, which intensified the events of the drama. The people who would enjoy BORDER are those who like supernatural dramas, the actor Oguri Shun, and interesting villains. However, there are other dramas who did all the above a lot better than BORDER, like SPEC.
