I've seen some other reviews, mostly bad ones, but proceeded to watch the show anyways..
This drama is really good! It's amazing! The thrill comes from the story itself rather than music and sound effects. Judging from the drama alone (since I didn't read the book which the drama is based on) each case is different, very entertaining, a lot of sad motives to the case yet there was no psychopath killer. I really like the calmness of the drama and it's up to the audience to feel or interpret the scenes.

It may look like Sherlock Holmes at the beginning but to anyone who wanted to watch this drama, I guarantee that this is original and it's not a copy of any famous work. Not sure if there would be a part 2 of this but maybe I could read the book for more of the cases. The only thing that I think was lacking (but not a flaw) to this drama is that I wish they show more about Hisame. I really do think that Hisame is just as good as Tori but it will all be explained at the end.
