Starring Scott Grimes, Dee Wallace, M Emmett Walsh, Don Keith Opper and Terrence Mann and released in 1986, Critters became a cult hit on video after modest success in theaters.
I saw Critters when it finally played on HBO and loved it. Director Stephen Herek (Bill and Ted's Excellent Adventure) made B-Movie gold. Obviously there wasn't much money for special effects, but even the cheesiest effect, which would be how the Critters get around (by rolling like bowling balls) is pulled off by either being funny or at least not distracting.
Critters was popular enough to spawn three more sequels, the second, also starring Grimes, Terrence Mann and Don Keith Opper, was the best of the three.
Bloody, silly and awesome, as good as Gremlins, Critters was a kick ass time.
Keep watching the sky, nerds!
