‘The Crazies’ is about a band of survivors trying to escape a small town where the citizens are succumbing to an infectious disease that turns them into rabid lunatics and, as if that isn’t enough, the bureaucracy is no friend, the army being a little less than helpful. ‘The Crazies’ is a satisfactory, if unambitious, remake of George E Romero's cult classic that delivers well on scares and hasn't misplaced its sense of fun (cue the most ridiculous groin-threatening set piece since Goldfinger).
