Well written, well cast, well directed, well acted; not a false note, which is rare in biopics. The reason we need movies like this is because (some) white people need training on how to be decent human beings. Racism is not a black problem -- it's a problem for black people, but they didn't create it, and they can't "solve" it. Civil rights, today's black lives matter, needs allies everywhere, until everyone are allies. I think the reason a film like this one, or like "Schindler's List", is so powerful is that if one group is so regularly dehumanized and degraded, it's "normal" (not dramatic) for them to suffer, or resist, but (almost) nobody cares about these "out" groups, whereas it's not normal for the apparent persecutor to switch sides. This isn't one of those films that suggests the black experience can best be appreciated through a white lens; instead, it suggests one way white-created racism can be appreciated for the ugly thing it is is through the white racist lens -- and this is a film about white racism as much as civil rights. When people in the film are so surprised that Bob Zellner is not an outsider (they assume he's a "northern commie Jew" agitator) but an insider, one of them, a good ole boy, it really brings the point home. The film makes clear that it takes far less courage for the protagonist to take part in a protest -- being blonde and blue-eyed, he can usually walk through a riot unharmed as if by magic -- than it does for the black people being beaten, but all the Movement needs is for SOME white people to exhibit SOME courage. Black people don't, by themselves, have nearly the legal, financial, legislative power needed to undo all the injustice, the racist laws and institutions, that persist to this day. As Malcolm X said, the South starts at the Canadian border, and "Son of the South" is a call to us other sons (and daughters) of the South to wake up, take up the civil rights cause as our own cause, and rally and canvass and protest and vote and work to build communities -- do things to actually feel proud of -- because the alternative presented by our modern-day racists, the "Proud Boys" and Capitol rioters, is just as ugly and stupid as it was 60 years ago. "Son of the South" doesn't suggest Bob Zellner is a hero (although compared to most of us he certainly is); instead, it honestly portrays a one-time racist from a long line of racists, who is trying to become a decent human being. It's a subtle thing, and makes the movie well worth watching.
