I've seen many white people giving this movie not-so-good reviews, and I think that may be the point.
People sometimes forget that the thing about a movie they "don't like" is actually a purposeful choice. White people aren't supposed to enjoy this movie. Just like the book, this movie is supposed to be awkward and uncomfortable, especially for white people. Richard Wright wanted white audiences to gain a greater understanding of what it means to be black in America. To him, this means a confusing, clunky life and an unsatisfying end.
I find the themes of the book and movie are incredibly relevant to today.
