This 30 minute documentary Buñuel made in the early 1930's about one of Spain's poorest regions is, in my opinion, one of his weakest films. First, let's admit that 70 years later, Spain is much richer than it was then (and when I say this, I fully admit that wealth can bring problems of its own, like excessive individualism and consumerism, though all in all wealth it's a far better condition than the extreme poverty portrayed here). And if poverty receded in Spain it was not exactly with the sort of socialism that Buñuel favored, but with Western European style capitalism. But one of the most shocking things about the movie is this: in one scene, the narrator chides that in school, children are taught the value of Pi. Teaching math to poor people, the horror!. Buñuel shortsightedness is at its most glaring here, not realizing that it is access to the latest knowledge and technology what will help the poor overcome their situation. What is he proposing? That children are taught exactly what at school? Doesn't Buñuel understand that it is the lack of modern technology that has made them poor in comparison with other people?
