Not enough background information on Gotham

Rating: 6/10 (7 April 2020)

The thing that disturbed me the most about the plot was how Arthur killing 3 "random" guys in the metro led to a massive upheaval in Gotham. What actually were the people of Gotham going through, that made them rally up behind a masked and visibly insane murderer? It would be a more compelling story if we got that background information somehow. Were people unable to find jobs? Were they underpaid? Whatever can explain their "grudge" against the rich...
Then, Arthur would also become a more believable character as well. Because, to me it was no surprise that Arthur was in poverty. He was a mentally ill person with a bad job. So, I did not feel it was right for him to blame to rich for his situation...
