For a mystery-detective drama about a team of investigators trying to pursue a vigilante named 'Darker', the entire premise success relies on how interesting Darker can be - and is well delivered. The Darker mystery slowly unravels by the crimes he brings to the public's attention, providing a side-commentary on society's dark underbelly. Crimes 'solved' then poses a question to viewers if Darker's methods are truly correct if justice can't be delivered via lawful methods.

Also, the investigation detectives are rather unique with their own skills and personalities. Although there was much initial conflicts and disagreements, the team really grew into a family-like dynamic as they share success and setbacks when confronting Darker. I feel that the team reflects as a positive mirror to Darker, as the two share many core skills and competencies while conflicting in their central viewpoint of justice.

Overall, a great drama and is worth a watch. The acting is superb with a solid story that twists and pulls in the individual cases, as well as the main mystery as to who Darker really is.
