To tell you the truth, I was expecting a great drama special because of its boost and everything. But after watching this it was a huge disappointment. The story is not interesting at all, it's confusing and the great co-stars are there just to promote the whole drama. I couldn't feel nothing else there. Even the dubbing of Wu Chun was very disturbing. (they should use different voice actor) Yamada's acting was very similar to his other characters (like in Hidarime Tantei Eye) and I couldn't see an unique Kindaichi at all. And Arioka Daiki was just an eye candy, I wished he would do more in the story. Kawaguchi Haruna was....well, she played 2 characters and we couldn't see any difference either. For me, this was a big fail and I can't give this more than 4 point overall.
