So far in my life, I've only seen two Senegalese movies: "Hyenas" and "Xala". The latter offers a satirical look at corruption.
The plot goes like this: following Senegal's independence from France, a crooked official - he makes sure that France still controls the country's resources - uses the country's money to get married for the third time. That's when poetic justice kicks in; he gets stricken with a curse called "xala", rendering him impotent.
If absolutely nothing else, this movie is a very impressive look at a culture that we in the west rarely get to see (and specifically, we get to hear Wolof spoken). Are the events portrayed cause for cynicism? Hard to say. But I recommend the movie either way.
