Michael Moore’s black-comedy documentary (1989) about the consequences of massive layoffs by General Motors in Flint, Michigan, and Moore’s unsuccessful attempts to buttonhole Roger Smith, the General Motors chairman, to bring him to Flint to see what his actions have wrought, is certainly impressive for a first feature, as well as bracing proof that movies can be both hugely entertaining and political at the same time. Mixed in with Moore’s justifiably lethal anger, however, is a certain sense of glib superiority over Flint’s victims as well as its corporate villains that one is invited to share, and the breezy results, while often exhilarating and never boring, are not exactly devoid of cheap shots and journalistic oversimplifications. (The cheerful heartlessness of Reaganism that is the film’s subject is not entirely irrelevant to its own methods.) By all means see this, but try not to feel quite as joyful about rampant stupidity, greed, and misery as this movie encourages you to.
