Critters (1986)

On an asteroid prison, a group of dangerous aliens known as Krites are set to be transported to another station. The Krites engineer an escape and hijack a ship, prompting the warden to hire two shape-changing bounty hunters to pursue them to Earth. Studying life on Earth via various satellite television transmissions, the first bounty hunter assumes the form of rock star Johnny Steele, while the second remains undecided, thus retaining his blank, featureless head. On a rural Kansas farm, the Brown family sits down to breakfast. Father Jay and mother Helen send teenage daughter April and younger son Brad off to school while waiting on mechanic Charlie McFadden. A former baseball pitcher, Charlie has become the town drunk and crackpot, with claims of alien abductions foretold by messages through his fillings.

Playing with overly potent self-made fireworks and Charlie’s slingshot, Brad takes the blame when Charlie accidentally shoots April and for Brad’s punishment he gets no dinner for the day. On the roof that evening, Brad mistakes the Critters’ crashing spaceship for a meteorite; Jay and Brad investigate and interrupt the creatures consuming a cow. The creatures thereafter kill and feed on a local police officer, and later besiege the farm and cut its electrical connection. While checking the circuit breaker, Jay is attacked by one of the Critters and, being severely wounded, just barely manages to escape.
