This is my first ever review on this site, so I hope I can put my thoughts into words!

I liked the cast and the actors, as expected with Korean dramas, always exponential acting. The story is the very typical over-the-top dramatics which I am not a big fan of personally, but if you're into that, you'll love this.

Now on to my critiques, I didn't like the borderline eugenics route they were trying to pass on for the first few episodes. I hated every second of the demonisation of people with antisocial personality disorder and the blatant misinformation. Not every single person with psychopathy is a killer in the making nor is every killer a psychopath, sometimes people are just evil. Many killers, yes, are mentally ill but what leads them to kill, in my opinion and many other professionals, is deeper than mental illness. If you've been watching Korean dramas for a long time, you'll know how hard it is to find dramas that accurately depict mental illness and this is not an exception to that. It's a critique I rarely see on this drama, which is a shame, especially if you're a mental illness-advocate. It is the running point of this drama so I think it's valid criticism since it's kind of the whole gag with this series. I did not feel fulfilled after watching it through and especially after the whole very unrealistic brain surgery and what not, I almost quit.
