There is something both exhilarating and sad here - with his debut feature, Xawery Zulawski, son of the famous Polish director Andrzej Zulawski (''Possession'', ''L'Amour braque'', ''La Femme publique'') has made a film far superior to anything that his father has ever directed. A daring and complex masterpiece, ''Chaos'' might very well be the best Polish film of the decade. It's a story of three half-brothers (their father having impregnated three different women without marrying any of them). One is an anarchist vagabond, another a successful businessman and a third a brutal and fascistic asshole. They seem to represent three different political aspects of the post-Communist Polish reality, but the way the characters evolve is both surprising and very politically incorrect. The old, out-dated assumptions about the Left and the Right get quite a thorough thrashing here, and by the time the film is over, a viewer might be totally confused if a swastika is supposed to be an old Hindu symbol of peace, a Nazi symbol of hate or just a simplified drawing of a hammer and a sickle. Witty, very intelligent, profound, deeply touching and tremendously entertaining, ''Chaos'' keeps the viewers on their toes, constantly surprising them at every turn. The humour is very understated, dripping with irony. The dialogue is often hilarious. The young actors are excellent; their performances surprisingly restrained, even thought the film is anything but.
