This Joker is the worst kind of wild card.
Gotham City is in decline. Most decent folk struggle just to get by. But decent folk are vanishing, as fear and anger infect the city.
Arthur Fleck is at the bottom of the deck, treated poorly by all. Many are too busy with their own problems to care. Others just see an easy target: a socially-awkward, mentally-unstable, failing-comedian street clown who still lives with his mother.
At some point, the soul-crushing monotony of mistreatment takes a toll, and Arthur lashes out. His abuse is heartbreaking to watch, and his indiscriminate, violent retaliation even more so.
Mesmerizing acting, scenery and music will disturb you from start to finish.
