This movie is a cinematic masterpiece. Just finished watching the movie a few minutes back. My mind is still racing thinking about the movie. It is a deep character study of how Arthur Fleck becomes Joker. He was driven to the edge of insanity and boy does he hit back hard. Gotham with all its lawlessness, corruption, prejudice, and insensitivity is rife for violence. His history is twisted. He feels lied to and is torn between truth and lies. The lack of empathy is something Gotham stinks of. He does not care anymore what is reality and what is fiction. It paints a grim picture of how the world is. It is grounded in reality and therefore one can relate to today's society. The ending is what transcends this movie into greatness.
