Time Out review:
This is probably one of the few great films of the Seventies. It's the tale of three Pennsylvanian steelworkers, their life at work, at play (deer-hunting), at war (as volunteers in Vietnam). Running against the grain of liberal guilt and substituting Fordian patriotism, it proposes De Niro as a Ulyssean hero tested to the limit by war. Moral imperatives replace historical analysis, social rituals become religious sacraments, and the sado-masochism of the central (male) love affair is icing on a Nietzschean cake. Ideally, though, it should prove as gruelling a test of its audience's moral and political conscience as it seems to have been for its makers.
Here (and above) is the trailer.
