50. ‘Silent Night, Bloody Night’ (1974)
Memorable quote: “I have wandered in bitterness until all seasons have become as one. And that is a season of vengeance.”
Scare factor: The movie that birthed the modern slasher flick. This forgotten classic—which takes place in Arlington, of all places—features the creepy atmosphere, disturbing backstory, and out-of-the shadows violence that have become staples of the slasher films of the ‘80s and ‘90s. Some mansions are best left deserted.
