I decided to watch this drama after being on my watch list for quite  a while. Although, it was only 8 episodes long it took me a week to watch it as i didn't enjoy it as much.

The last episode was the best episode in my opinion. I watch the other episodes on fast speed.

Thrillers are my favourite genre, psychological thriller is even best.  However, it was really hard finishing this. The acting, in my opinion, was not the best which I understand as it appeared that for some of the actors this was their beginning acting piece.  The acting was just cringe worthy.  

The story plot could have been better but it was interesting, nonetheless. The scenario reminded me a lot of 'Lord of the Flies' which showed how even normal humans can become monsters given the circumstances.  I do think the plot could have been better portrayed.

The characters were annoying. There were only two characters I liked which was portrayed by Kim Woo Bin and Sung Joon. The girl was annoying, in my view, and I honestly didn't understand what the big deal was with her and how the majority of the male characters liked her.

I do think that the killer did help them in some twisted, demented way. They had to face their issues which was the right thing to do in order to fix it.

I wouldn't watch this drama again and I wouldn't recommend it to anyone.  

The drama did end on a good point and the drama did pose a good question: are monsters born or created?
