I heard amazing things about this show. Knowing how hardcore fans can get rabid about "awesome" shows, I can reluctant to watch it myself. I'm sorry I waited so long!
The show mostly revolves around Osawa. It flips a little between her personal life and her extraordinary detective skills. I'm happy that they didn't delve too far into either arena. The show would have sucked if it was based on "You can't get a husband." On the other hand, I think it would have been too dry if it focused solely on the detective work. It was a great balance between the two.
I'm not going to go into each of her subordinates individually because that would take way too long. I enjoyed seeing the transformation of Kimoto Mami (Toda) from a stand-offish loner into an actual part of a team. Since there is a second season on the way, I hope to find out a little more about Iwai (Kendo) and Yamamura (Nukumizu). They were great secondary characters but they seemed to get tossed out to make room for everyone else. I'd like to see them make their own transformations.
This is most definitely a must see. Don't wait!
