It's gonna mess with your head. You aren't going to want to, but you have to pay attention to catch the clues and emotional nuisances that drive the story. All the movies depict a dark and animalistic side to human nature. The characters are broken and greedy and grasping for any ray of hope or happiness they can take for themselves. Even when forced deeper into darker dealings. They want happy things, but they aren't looking in happy places. Moral of the story, everyone is an A-hole.
