Very good film. While I don't think it holds back the film per se I did want to know more about who O'Neal and Hampton were as people. Nowhere in this film do we get an idea of O'Neal's life outside of his informant role and while we get glimpses of the personal life of Hampton through his relationship, most of it remains on the surface level too.
As far as the narrative focus goes though it is a well-paced and effective thriller drama, with great performances from both Kaluuya and Stanfield. And due to high dedication and care to its historic time frame it feels authentic as well, which definitely helps set the film apart.
