This is an interesting movie revolving around a world where humanity is on the brink of extinction. All I can say is "Reality sucks." The movie tells us how we'll act accordingly if we are on the same page as those in that movie. The one who is strong gets chosen to be a leader without doubt. When there's a leader, social classes exist. People whose up will be safe, while others whose down below get thrown and neglected. Even though it's unjust, when life is the only thing left for us, we have to make a choice. Those choices that we made might bless or hurt others. Interestingly enough, this kind of societal behavior does not only exist in the specific situations of the movie. In reality, there is something like this.

I really love the acting here, especially by Lee Byunghun, Park Seojoon, and Park Boyoung. I didn't really pay attention to the music, but some parts were louder and some parts were just right. Overall, great movie. I might not rewatch this, but this was an eye-opener.
