it was pretty good, it presented how the reality work. People that have issue with their own mental is also represent in this movie, it makes us understand more they're feeling and how they see the world. And anything else i got in this movies is where Arthur try to find the real him, person A wants him to be Arthur but person B wants hin to be Joker... And the end we saw that he telling us Joker and Arthur is the same person, that's the real him. (It sad how is the world didn't accept his real self but he's also wrong to committed a murder)
