this 30 minute documentary buñuel make in the early 1930 about one of spain poor region be and in my opinion and one of his weak film . first and let admit that 70 year later and spain be much rich than it be then ( and when i say this and i fully admit that wealth can bring problem of it own and like excessive individualism and consumerism and though all in all wealth it a far good condition than the extreme poverty portray here ) . and if poverty recede in spain it be not exactly with the sort of socialism that buñuel favor and but with western european style capitalism . but one of the most shocking thing about the movie be this represent in one scene and the narrator chide that in school and child be teach the value of pi . teach math to poor people and the horror . buñuel shortsightedness be at it most glaring here and not realize that it be access to the late knowledge and technology what will help the poor overcome their situation . what be he propose . that child be teach exactly what at school . doesn not buñuel understand that it be the lack of modern technology that have make them poor in comparison with other people .
