I started this solely for the female lead, and found the first episode heavy going. The side characters, like the Chief of Police and the incompetent superior officer, seemed like caricatures, while the male lead was very shouty. Happily, things settled down and the Drama started getting smart, both in the storylines and in the developing relationship between the leads.

The female lead is an interesting character, bright and motivated, and also discreetly conflicted. By that I mean her inner angst remains largely inner. That inner conflict was brought into VERY sharp relief at the very end of the final episode and was responsible for me upgrading my score from 6.5 to 7.
