Our Christmas viewing returns with a winner: Black Christmas (1974). Derek and J.R. discuss, among other issues, why this movie works: the voluble, unhinged killer is unsettling, the movie surprisingly portrays the emotional aftermath of violence, and the tone is generally ambiguous and realistic. It ain’t all roses, of course, with some lame shoehorned humor and weird character actions. J.R. also reminisces about his idyllic childhood spent prank calling messages of mayhem.
