Black Panther impresses in several ways. Structure is one of them.
The midpoint of the film is a great example of "the first culmination as midpoint."
We get a cascade of events which lead us to a true twist. Not only is the truth of Wakanda coming out as a result of the club chase and Klaue's interrogation, but we also see a tear in relationship between T'Challa and W'Kabi upon the mission's failure.
The final curve is our main character's family truth. We find out we have a cousin, powerful, fighting for a cause that may have been born from our own but is now in direct opposition to us--my cousin is my enemy. Our reality has shifted.
(Directed by Ryan Coogler, written by Coogler and Joe Robert Cole, based on the Marvel Comics by Stan Lee and Jack Kirby.)
Be well.
