An absolutely grotesque horror film based on the book by Shaun Hutson, this bloody shocker from Juan Piquer Simon (Pieces) is set in a small town in upstate New York but has a mostly European cast. Hordes of mutant flesh-eating slugs are having the citizenry for lunch until a trio of public officials takes action, as is standard procedure in the post-Jaws ecokill film. The gore is excessive and quite well-handled, particularly a scene in which two nude lovers are literally ripped to bloody bits in a bedroom full of slimy horrors, but otherwise the film is surprisingly uninvolving. Fans of gross-out cinema will still want to catch it for a scene in which a restaurant patron's eye blows out, revealing swarming baby slugs. Needless to say, such doings will not appeal to everyone.
