Reading all these 10 Star reviews, i feel like having to explain why I've been disappointed

Rating: 7/10 (29 October 2019)

First of all: yes, it's a good movie. Well acted and very convincing.
But: This is not a story about the Joker.
It is a good story about someone who is sick. About a Society that doesn't care. About someone who breaks - and coincidently is dressed as a clown.
The Joker - as far as i can recall - is a very brilliant (super) villain. He doesn't have superpowers so he has to be clever. He has to be always one step ahead in order to take on Batman.
This guy is not clever, he is just a poor guy dressed as a clown.
