Once a vision of a future where the world is run by corporations who keep the public distracted with extreme sports seemed plausibly distant; now it feels like a fucking documentary. It's flawed - like most futuristic visions of its era, it only succeeds in successfully predicting the fashions of 1976, and the Dude vs. The Man story a bit naif. But Norman Jewison's sly style contrasts an eerily serene world of modern architecture and technological advancement with the hyperkinetic action and crunching violence of the title sport. This current zeitgeist cries out for such anti-establishment films, and it stands as one of the best '70s sci-fi films, which all had a strong element of social metaphor or warning to them.
