Through the darkness is about the person eho became the first profiler of SK. Its based on his experiences, so if you are here to watch some kind of major plot twist this is not your drama. Feel free to not watch it rather than calling it a boring drama.
All the cases, as far as ik were real cases.
And the acting, woahhhh, i mean be it the offenders or the main team all of them did such a good job. You will actually feel that nauseousness when you come across some acts done by the myrderers/rapists.
The drama is a door for you to know how the mind works of a murderer.
THE DRAMA IS PHENOMENAL WITH BRILLIANT ACTING. YOU ARE MISSING OUT ON A GREAT DRAMA JUST BCOS YOU ARE "FAN" OF MAJOR PLOT TWISTS IN A THRILLER DRAMA AND FIND THIS SLOW.
