B-movie science-fiction with a terrific, eerie start in the company of a woman waking up after a failed suicide attempt, with no power or services in her apartment and no one out and about – on first inspection – out in the city. As the film picks up speed, it’s still watchable, despite the stock footage and creaky characters. Right up until the shadow of the killer robots themselves. After that, things fall away dramatically. While still vaguely entertaining, the signposts and formulae point but can’t deliver the ending quickly enough. A great start to the film, nonetheless, though even for those who are adept at suspending disbelief, this is a test.
