Do you mean you think the story of Joker did not really do enough?
Story-wise, I thought Joker was a pretty solid alternative universe take on how Joker became who he was, whilst setting up the origin of Bat-Bat.
Don't get me started on Black Panther....
I thought BP was one of the dumbest and weakest MCU films to date, and that it was only nominated because of the 95% black cast.
You think Phoenix was more worthy?
After first watching Joker 2019 I thought Phoenix was the best live action Joker ever, but then later... I realised that the full expression of The Joker's ideology can only be revealed when in contrast to Batman's, thus in a way, Ledger's portrayal is still better.
