Saw this with the daughter, it was brilliant and perfectly captured the experience of being black in America. Not that I'm in a position to know, but the general tone - the references to "I Voted for Obama" and "Tiger Woods was the best Golfer" - the pure vanilla of the girlfriends family, the scene where he's forced to watch the "happy white american family" on the TV - it works on a lot of levels. The twist, well, it's good, but hardly necessary, all the horrors of cultural appropriation and assimilation are there well beforehand...
