Controlled opposition in my opinion. Nothing more.
Presumably, most things are.
The movie is banned in my city though, which I consider suspect. The more the mainstream machine promotes something, the more I assume it is controlled opposition.
For people to say Joker was a movie going against the established status quo is nonsense, given it made something like $1.1 billion.
That being said, I won't complain about a movie raising awareness about child trafficking.
