To tell the truth, I watched this drama because of its title. The plot seemed original enough so I had high hopes for this drama. The story was great with all the potential of turning into something reminiscent of the X-files. But the drama predictably ended up being showcased in the typical Jdorama formulaic fashion. The acting was mediocre considering the actors in this drama have a whooping range of five emotions; sullen, murderous, angry, scared, and frustrated. This drama's only standout is found in the character of Detective Sakisaka. The music was this drama's saving grace, the bgm was wonderfully tasteful and totally unlike the usually annoying sounding loop music typical of jdorama mysteries. If you like paranormal Science-Fiction, twisted mind games, and mad scientists(and the patience to survive the mediocre acting and the awful formulaic episodes), this one's for you.
