100/10. The amount of times my heart dropped is wayyyy tooo much. Every other moment was a moment of suspense and anxiety. Not watching this film is going to be the BIGGEST MISTAKE of your life, so better watch it ASAP.
And I don't know what's up with the Korean film industry but they always make Psychopaths good looking.
And I am Hella impressed by the duality of the actor Im Si-wan. I couldn't believe he was the actor from Summer Strike and Run On.
