My Bloody Valentine (1981)

Twenty years ago in the sleepy mining town of Valentine Bluffs, a fatal mining disaster occurred on Valentine's Day while key members of the crew were decorating for a party. The sole survivor of the accident killed the absentee crew members and warned the town never to have another Valentine's Day celebration. When a group of teenagers decides that the the town has gone without a party long enough and begin planning one, a murderous maniac in mining gear begins dispatching townsfolk in bloody and creative ways. Combining the small town atmosphere of HALLOWEEN (1978) with the body count gore of FRIDAY THE 13TH (1980), MY BLOODY VALENTINE is an example of the glut of low-budget copycat films that those two influential films inspired in the early 1980s.
