Kyle Arguelles’s review published on Letterboxd:
We really need to talk about LaKeith Stanfield's performance in this film. Depicting a menace to society is no easy task. Regardless, his portrayal of Bill O' Neal is just as convincing as Kaluuya's performance as Fred Hampton. The overwrought character of a man that finds himself betwixt between social revolution and self-seeking gratification, with this character having horribly gone down the latter path.
Telling stories matter, especially those that define moments of history. Appreciating these artists, given what they go through, should go without saying as well. I later found out that this role had resulted in emotional distress for LaKeith and that he had to go through therapy after filming.
The events that transpired in 1960s Chicago had ended bitterly with the iniquitous murder of Fred Hampton, but the justice he advocated for and believed in remains alive in the hearts of many people.
