Despite the raving reviews, I wasn't drawn to this. I attentively watched 3 episodes and skimmed the rest. It was boring and dragged for me after what happened to the family. It was like an episode of Criminal Minds with some background drawn out to 20 episodes. It also reminds me of a Webtoon "It's Mine" which started out well enough but is also getting dragged out to who knows when.

I guess I'm used to watching serial killer type dramas, and nothing was significantly new here. I couldn't get into either the main characters or victims either.
