I would rate it 4.5 /5. It's a good kdrama. I found first three episodes boring because I wasn't able to understand but from fourth episode it got interesting. It has twists in every last episode. If you like watching thriller kdramas then give it a try. I watched Shin ha kyun acting for the first time & it was impressive. Yeo jin goo also acted good. I watched him first in Hotel del luna. He acted really different in this kdrama. Some people compare it with flower of evil but I think flower of evil is better than beyond evil.

If you're a fan of horror genre give it a try. It's my first horror kdrama & I enjoyed it till the end. You want to know till the end who is park il do & why is he doing all this? It's main characters are: 1. Kim Dong Wook as Yoon hwa pyung: He performed reall well. I watched him for the first time. He looks a little like Song joong ki. 2. Kim Jae wook as Choi Yoon/ Mateo. He also did well. I have watched him in her private life kdrama. 3. Jung Eun Chae as Kang Gil young. I watched her for the first time as well.

In starting this show seems a little boring, but with time you get hooked to the show. Um ki joon is good at playing negative characters. Show has some emotional scenes but it doesn't makes me cry I don't know why. I felt bad for lee sung gyo & park Jung woo. Supporting characters are also good like Jung woo's prison mate. They makes us laugh. Overall you can watch it for once. I would give it 4.5/5.
