Gist, it's more twisted than the poster made it out to be, but it gets you clicking "next" regardless. Also, it's my bad for not reading the tag properly. It does have "slight horror" tagged on it lol

The acting is top notch, crazy action-packed adventured filled with plot twists. It's SO good! If you're looking for a thrill, you're in for a ride!

The only thing that bothered me is how the father turned out in the end. I am not a fan of the father taking revenge because he lost the bigger perspective of life. While chasing for murderer, he is losing the only family he is left with now. I mean...what if the son ends up having a murderer as a father? That is even more cruel than what had already happened.

For that reason, I really get quite disappointed towards the end, despite the murderer being a real psycho.

Also, if you're not into dark story, you could skip the parts where the murderer is retelling his story. After this storytelling, the action gets real good. I didn't regret watching it, I just wished I had skipped those dark story, because it's not really necessary to understand the whole drama.

Overall, I think the show is very well done and is probably the best thriller I've watched in terms of the excitement it gives you, though not necessarily my personal favorite for the reason above (about the father)

Watch it and judge it for yourself!
