This series has good plot outline - I am someone who is quite fond of mystery, horror investigative series, this series falls loosely in this genre. I have only watched 4 episodes and I am dropping it.
This is mostly a comedy centered series .... I am a hardcore mystery horror and detective enthusiast ( strangers in hell(kdrama) psychopath kind of level)...So for someone like me this is kind of disappointing and not my cup of tea. So if you are like me try watching 1st episode and if it doesn't suit you can drop it.
But it also doesn't mean it is cringe or comedy all the time human emotions that drive you to commit crimes are portrayed seriously pretty well too...but it still wasn't enough for me to overlook everything else.
In short say u love something very unserious and just enjoy without exerting too much brain and enjoy melodramas here and there this might be upto your lane.
At times I thought they could have done better with cases and had more serious approach at least like THE GUARDIAN......

Anyhow the above review is personal opinion and purely subjective.... You might find it different considering on your tastes.
