I’m not qualified to comment on most of the thrust of this piece, but there are two manifest elements at play that you are drastically overlooking:
1 — The vile allegations against Nate Parker, and more important, his woefully inept (at best) handling thereof in interviews and media appearances, and how that interacts with box office receipts. As Roxane Gay stated about the film, separating the art from the artist is impossible for many who have personally interacted with sexual assault — and even for those who have not.
And, adding insult to injury:
2 — The fact that the film is poorly made.
Honorable mention goes to, as has already been pointed out, the overwhelmingly female skew of the audience that DID open the film. Blaming Black Feminism for this film’s failure only works if you ignore the writing on the wall, it seems.
