First, i am a korean movie lover since 2000 when i watched JSA. I am still a crazy about their movies. So when hear-say that one was Korea biggest hit, I watched it. It is confusing, kinda boring but the worst is that it is a pale copy of « usual suspects » Si, si, think about it. But it isn'it subtle as the original. I found out who Mister Lee is way too soon. It is unusual for a korean director to copy that much and that poorly another movie. It is more common the other way around. The sequel is just release on Netflix France. I won't watch it, the first one is too bad. Not anyone is Park Chan-wook.
