This drama was recommended to me by a "kindred spirit" and now I'm wondering why I haven't watched it any sooner.
I was captivated on minute 1 and enjoyed the whole ride till the very last.

The true strength of this show lies in the characterization. I love the speedy way in which each character is introduced, without unnecessary premises: the viewer is immediately catapulted into the birth of this new police division and the methods which are going to be used by the team to solve each case.
The staff members come to life so swiftly and clearly, I was eager to see the next episode just in order to hear them interact with each other. They are hilarious, over the line like any true Japanese character and yet so believable and endearing.
And then there is their BOSS. Yuki Amami is a wonder here. She's determined, beautiful, self-ironic, tremendously intelligent. The kind of woman I'd like to be at forty - honestly, if I could only look like her at 44 I'd be the happiest woman on earth.
Her character is a riot and a model of what I call class.

This is an episode drama, therefore it can be viewed either in one raw or taking time between one episode and the next. I did a marathon because each case left me wanting for more, but there isn't a main sub-plot which requires steadfastness.

I liked the music too: it isn't an unforgettable original soundtrack, but it highlights the scenes with due pathos.

If you're looking for a clever detective story, with some profiling/psychology, lovable, funny characters and intriguing crimes, watch this.
