I didn't see what people mentioned below, that this is like BR. No.
I watched this after BR and this one focused on the psychology of different people in the story when pushed into their limit in not only survival but on their emotion as a person and how they perceive other people and their environment, hence the title.
Unlike BR it focused on the "survival of the fittest".
This is how I see they differ.
The big question wasn't directly answered but was implied. It was showed at the end after the screen went black and showed some credit, you must've missed it and a lot of people did, but the answer was there.
I was glued on the screen the entire time. The acting was flawless, it was an amazing ride watching these actors make you believe that they're not in a movie. This movie effectively portray its message and told the story well. I'm just new to historical dramas so I can't comment on it being great among the others.
I have to say the ending was something. It left us thinking about things that we are afraid to admit. I just can't figure out yet whether a second season is good, or what kind of story it should have. Nonetheless, its a good drama.
