Rats eat corn which inexplicably is coated with steroids and grow into large rats with nasty tempers, huge teeth and seem even more intelligent. Science teacher Sam Groom and health official Sara Botsford find out and try to save the city (carefully not named but it was filmed in Toronto).
The plot is old hat but this is reasonably well done. The script is OK and the acting is pretty good (especially Botsford). But what really makes me give this a 7 is the rats. Yes, I know they're dogs in rat suits but they look convincing and the scenes of them chasing victims are scary. Also the attack scenes (especially the one in the theatre) are vicious, bloody and very gory.
So a worthwhile movie for horror fans--especially those who like early 80s horror (like me). But if rats bother you, stay far away from this!
