First appearance: Critters (1986)
Small ravenous alien criminal carnivores steal a spaceship and crash in a small rural american town making life miserable for the family they land near. Luckily bounty hunters UGG and LEE are on the case! The town drunk gets a new lease on life.
One of the better "little monster" movies to come out in the "let's make another Gremilns" era of filmmaking. Spawned 3 sequels (two more than Gremlins) and started the tradition of "We've got to set one chapter of our franchise in space" usually Part 4.
