Umm i like this show, it may not be too sensational, but my husband and i enjoyed the show. It has a couple of good cases in it, like that crazy ahjushi or that couple who murder the kids. The case is not overly lengthy and it’s not too focusing on the emotional part, which i enjoy. I don’t like lengthy episode just to fill in the screen time like typical kdrama. There are some emotional parts inside too that tell the story about the killers on why they commit the crime etc. i think it’s pretty good. Maybe it’s because I don’t watch Americans’ criminal minds. I don’t think it deserves 7.9 stars coz there are many bad kdramas which have above 8.0 stars. 7.9 stars is too low for sure, this show is certainly above 8.0 in my opinion.
