This show made me cry for a serial killer - that takes a massive amount of talent and skill. It was so well done, the acting is amazing, the story left me guessing and praying as to who the actual killer was, it was just amazing. There are some parts that strained credulity, like I just couldn’t buy into it as even remotely plausible, but they played an important plot role, so it ended up being well done. There were some parts where I couldn’t tell if it was a flashback and got a little confused, and one part where it seemed to just jump to something entirely different without explanation. I wish that had been clearer. It’s possible I just didn’t understand due to not being fluent in Korean and mostly reading subtitles.

Overall I thoroughly enjoyed it; I was glued to the screen every minute I possibly could be, and was thinking about it when I was not. Just an astounding acting job by the two male leads. I am not usually into scary stories, but I loved this. I want to watch it again to see what I missed the first time around.
