Again thanks, Cameron and Rose. You are largely in agreement re characters and their respective functions in the story.
Protagonist: Ron and as a secondary Protagonist Flip.
Nemesis: Felix and Connie.
Mentor: Bear in mind, there are Positive Mentors and Negative Mentors, so Trapp and Kwame Ture slot in quite comfortably into those roles. How about this: Negative Mentor = David Duke. He espouses a world view which is contrary to Ron’s world view, but it is a coherent, if bigoted take on reality.
Trickster: I concur that Bridges fills that role.
BlacKkKlansman is yet another movie in which we see these five narrative dynamics playing out in terms of the story’s central characters.
