Frustrated. So many things could've done better. The story only focus on the useless and incompetent police officers which I don't understand why this become the main view while the story could focusing more on the perpetrator himself. How he ended up being like that and such. And the reenactment scenes also doesn't make it sounds or seems thrilling to watch. This can be squashed up into one episode rather than stretching it out too much into three parts. Slow paced with no guarantee of clear closure for the viewers is risky.
