Unreasonable & gloomy movie

Rating: 3/10 (14 October 2019)

Cannot understand why this movie gets high score. The content is so bad, gloomy and unreasonable. It is exaggerated too much. How can a mad guy who kill 03 men become a symbol for a mad society??? How can rich men always badly treat or make difficulty to poor guy??? Any reason for a mad crowd tries to protest a senator who is just only standing as a candidate for President position???
Three stars for the good performance of main character.
