THE BRAIN EATERS (a great title for a sci-fi flick, by the way) is a pleasingly old-fashioned 1950s-era B-movie which involves an alien invasion along the lines of INVASION OF THE BODY SNATCHERS. It's a low budget affair but one which tells the brisk story quite efficiently, beginning with some scene-setting involving an alien craft and building to the usual takeover and action sequences. It's not a classic like INVASION but it does the job well enough and manages to entertain for the hour-odd running time.
