The best R-Rated comic book movie since "Logan"

Rating: 9/10 (14 October 2019)

Todd Phillips and Joaquin Phoenix team for an unconventional comic book movie about a man and a city's descent into madness. There has been some discussion that this isn't a comic-book movie, but it undeniably is. It is an origin story.
Arthur Fleck is a devoted son. He lives with his mother, but he is not dependent on her. Rather, he takes care of her, and he does it by working as a clown for hire. His job takes him to various places: for example, a music store going out of business and a children's hospital. Arthur also suffers from a (real-life) condition, which causes him to laugh uncontrollably at inappropriate times. So much so that he carries a card that can explain it to people when he cannot.
The construction of the story is masterful and subversive, and it requires the audience to think and deduce some of the action going on before them.
Phoenix's performance is nuanced and skilled. It captures some of the cartoon-like nature of The Joker without it being cartoony. In some form, you respect Fleck's struggle, and then he shocks you with his behavior. In a sense, Fleck has a code, and until the very end of the film, he never violates it.
To tell you more would spoil the experience.
Rated R by the MPAA for strong bloody violence, disturbing behavior, language and brief sexual images, Joker is the best comic book film with that rating since Logan. I highly recommend it.
