This great film will come as a great shock to anyone who thinks of 1950s America in Leave It To Beaver terms, and that's a very good thing. An exaggerated but not misleading portrait of a hugely racist and sexist nation at its worst, with a feel-good conclusion that rings false in light of what we've just seen and generally know to be true about the US at the time. The performances are good for the most part, but the things these people say and do may give you the creeps. The scene in front of the city hall when the local white men are about to use nitro to blow up the front door is absolutely frightening. The 50s will never seem the same again, and that's a very good thing. This movie should be part of history courses.
