I know that everyone says "best tv series ever" on almost every Korean show review, so here's what I'll say, because most KOREAN series are too freaking awesome and exceptionally executed, I'll say this is the best political psychological thriller I've seen thus far.

All the actors are great. No wasted meaningless scenes. The main character is quite intriguing. Cho Seung-Wood does a fine job at portraying prosecutor Hwang Shi-Mok.

The way Lee Joon-Hyuk plays Seo Dong Jae makes him my top two fav characters, right next to the protagonist. Didn't know he was so good. I had only seen him in "Are You Human".

This show is so unpredictable. Many scenarios throws you off when new speculations, questions and events are raised.

I especially love how the story depicts Hwang. He is unable to feel emotion, because of this, he is able to carry out his investigations without any bias which makes him a fair prosecutor, but we also get to see the flaws of his condition as the story progresses.

Many of these characters are multi-dimensional, and we don't really know everyone's true intentions, which keeps you on the edge of your seat every step of the way.

Screenwriter Lee Soo Yeon deserves props for this. The writing of Korean tv-series is remarkable.
