That would make sense if it were truly possible to separate the two. When it comes down to it, the story is about Vance, his character is still named J.D. Vance in the movie, and critics and audiences are widely aware that the movie was adapted from a New York Times bestseller. This explains why the film is getting critiques like “A sickeningly irresponsible parade of death and despair” from the Independent and “Elegy is entirely true to Vance’s book, which is the worst thing I could say about it” from Vulture. For entirely different reasons, the National Review doesn’t like it either.
