The plot delves into the psychology of a murderer, understanding their intentions, and using the data to categorize murderers into some sort of personality types. I found the idea to be rather interesting as I personally like psychological thrillers. However, this series failed to hold my interest till the end.

One would expect thrillers to be 'gripping' and you would want to hold your breath as they challenge the murderers and uncover details of the case. This was only largely seen in the first story in the series. Honestly, Part 1 of this series was captivating. The first few episodes were great, and shows promise to this series, however as the series progressed, I found myself skipping through the scenes. The acting was amazing, especially some of the prisoners they interviewed. However the series failed to explore more details in the psychology of a murderer, and somehow the crimes get more easy to solve. It seemed like a disappointment from the first few episodes and furthermore, there wasn't much character development. It was just a monotonous solving of crime after crime.

Overall, a mediocre thriller, not as dark as I would like, but it's an interesting watch for sure.
