Superb acting but poor directing, poor character development

Rating: 5/10 (9 October 2019)

Joaquin Phoenix acting was superb, but the director failed to make audience feel the character development of the joker becoming evil, mastermind of crime and manipulative. Director make audience feel that the Joker is weak, pathetic, bullied by society, yes he did a great job, we do feel sympathize for Joker. However the message of Joker becoming a killer, evil mastermind was poorly conveyed and portrayed. It feels like all of the sudden, Arthur Felix able to kill people without actually showing motive to kill people, he doesn't seems to be enjoy killing people. Joker supposedly enjoy committing crime he planned and he laugh whenever he enjoys it. But in the movie, Joker is still weak and pathetic until the end.
