Great from a filmmaking standpoint but the narrative couldn't have been more one-sided. The villains are portrayed as bigot simpletons who were on the wrong side of history, and the end titles flat out state that public housing was a success.
Spoiler:
Pretty sure they state that those specific public housing town homes were a success.
And I can see why the seemingly one sided narrative irks you, but it's a drama based on a novel, not a documentary based on a history book. And with that being said, do you have any evidence to the contrary, or are you simply bothered by their characterization because you agree with their policy positions?
All that aside, I agree, great film making. It's really an exciting time for cinema.
