"The 6th Day" is a rarity: an Arnold Schwarzenegger vehicle with a plot (with a great reversal in the middle), a weighty subject matter, and something to think about. Even the villain is not just a random psychopath - he has a rationale to his actions. The film is well-designed (the world it creates is both recognizable and slightly futuristic), and sometimes very funny ("loading virtual psychiatrist!"). And how about Robert Duvall's performance - certainly of a higher caliber than we're used to in an Arnold film. It's not flawless: it's too long, some of Roger Spottiswoode's directorial effects are annoying, and the helicopter climax looks very bad! But as Arnold's movies go, it's among his better ones. *** out of 4.
