Best Origin story of the Joker(MAJOR SPOILERS!!)

Rating: 10/10 (13 October 2019)

I saw the movie this weekend. I had very high hopes for the movie.
When I saw it, it was better than I expected. The movie deals with psychology about a man who lives in a society where rich and poor are divided. The film states the main problem:Social classes. Rich are given more importance and the poor are made to suffer and live impoverished lives. Arthur is suffering the most throughout the film.
Examples of social classes are shown throughout the film:One in Particular is the train scene where three Wayne Enterprises businessmen are bullying a poor girl and this reminds the Arthur about his life. He yearns to be noticed and wants to be recognized, but Gotham never gave him a chance and mentally and physically abused him. While he did do bad things in the movie, there were many reasons that pushed Arthur over the edge:
1. He was beaten up by a group of teens(I hate them) and left there crying. His boss was angry at him, just because he lost a sign?!, not because he was assaulted!?
2. A guy he thought to be his friend gave him a gun for protection, but when it was revealed, he used Arthur as a scapegoat. Arthur was fired for something his friend did. This explains why he killed Randall, but spared Gary, since Gary WAS nice towards him.
3. His adoptive mother Penny abused him and gave him a head injury, that caused his uncontrollable laughter.
4. His favorite comedian host made fun of him by playing his laughing video. Throughout the film, Arthur wanted to be like him and imagined him liking him, but in the end, he was just like the rich, spoiled people of Gotham.
Therefore, the Joker ended up getting at the end what he wanted his whole life:respect and fame. The Clowns hailed him as a hero and it put a smile on his face, even when he was imprisoned.
Amazing movie! This should be made canon to a DC movie. Joaquin Phoenix delivered an amazing performance.
