It is a film that embodies the story of an orphan raised by nuns (Lillian Chauven, Gilmer McCormick). With the passage of time, this orphan grows into a play store for a killer of Santa Claus, because of his stay in an orphanage and perhaps this orphan was subjected to a bad path throughout his life and was abused by the mother superior, which caused him to become a murderer.
This was obviously not new territory for the slasher genre, mind you, but Silent Night, Deadly Night brought the idea to new levels of cold sleaziness.
Among the dozen or so victims of Santa's slay ride is a man who's choked to death with a string of Christmas lights and a young woman who's impaled--topless, of course--on a pair of moose antlers.
The psycho Santa embodies Reagan-era conservatism, then at its peak, mocking the strict discipline of compassionless, law-and-order, moral-policing reactionaries...If the Gipper was post-Carter America's Santa Claus, he was also its Krampus.
