A classic of science fiction and the paranoid political thrillers prevalent at the time: chilling in its implications and persuasively presented, the film makes for intelligent if demanding viewing. In hindsight, while it's much admired by connoisseurs of either genre (being a fan of both, I'd been longing to catch up with it for years!), the film deserves to have a more widespread reputation. Undoubtedly, this remains Joseph Sargent's best work; his cinematic career hasn't provided much else worthy of note, with the only film to come any close being the fine caper THE TAKING OF PELHAM ONE, TWO, THREE (1974).<br /><br />Its computer-run-amok theme echoes the Hal 9000 of 2001: A SPACE ODYSSEY (1968) and looks forward to DEMON SEED (1977)'s Proteus IV; what a fascinating if overwhelming triple-bill the films would make! Where production values are concerned  polished look (courtesy of d.p. Gene Polito, who later shot WESTWORLD [1973]), imaginative settings (by the veteran Alexander Golitzen), often disorienting editing (the expert work of Folmar Blangsted) and an appropriately weird score (by Michel Colombier)  the film truly can't be faulted, but it also benefits from a largely anonymous cast. The abrupt and unresolved ending, with Man refusing to give in to the undeniable superior intellect of his creation, is highly effective and certainly left the audience with sufficient food for thought  and even apprehension  for the future.<br /><br />Needless to say, when this was announced for DVD release, I was ready to leap at the chance of finally being able to own and watch the film  but, as many of you must already know, my joy (and that of many another fan, I'm sure) was short-lived when it emerged that Universal had issued a Pan-and-Scan version (which I can only imagine now how this ruined its detailed widescreen compositions)!; thankfully, I was able to make amends via the miraculous format called DivX...
