Have you seen the movie Gremlins? Well then you have a good idea what the movie Critters is about. Basically a small town is overrun by little monsters who are a mix of scary and kooky. Most people think Critters was a Gremlins rip-off but work actually started first on Critters. While Gremlins eventually had a sequel Critters cranked out 4 movies, the last one was set on a space station in the future ala Jason X and Jaws 6: Space Jaws.
They don't really make movies like Critters, or Puppet Master anymore (scary movies based on silly puppets) I'm not sure if that's due to the fact that CGI has become so prevalent or because they were often bad movies. But look, Nardo Di'Cap!
