I don't like that of all things comic characters (I don't care for comics and think they're juvenile anyway) are the top cinema 'trend' today. They're all stupid and overdone to me now.
That said, this installment of Joker is refreshing and has managed to piss people off in the right way. It really takes home that yes, fucking (ie. Bullying) with people can lead to the inevitable. And I don't blame the victims of bullying much at all.
Fuck society that rewards sociopaths and criminals (the current US President, major billionaires, or even just your corporately enabled low-level shitsack to make your life hell, etc) that turns around and cries when the victims say fuck it and play by their games but without Chad-tier popularity/social bullshit acceptance.
Society is all fake bullshit that hurts almost everyone but the entitled. Joker just says fuck it, people are stupid and evil. Be less like that and Joker wouldn't have to become.
