La Mala educación

One of Spanish master filmmaker Pedro Almodóvar’s best, most complex, and most daring films, La Mala educación (Bad Education) twists all the conventions of the film noir genre to deliver an intelligent, touching, and quite disturbing film that works as a psychological study of shattered minds, as an indictment against hypocrisy and abuse of power, and as a vivid demonstration of the director’s love for the art of cinema.( Alternative Film Guide)
