Christmas Evil

From today's Toronto Globe:
Christmas Evil, The obscure 1980 slasher film - which by today's standards plays more like a low-budget psychological drama - has become something of a cult classic in recent years. A 2006 DVD includes audio commentary by none other than John Waters who deems Christmas Evil "the best seasonal film of all time," adding, "I wish I had kids. I'd make them watch it every year and if they didn't like it they'd be punished."

The director has the only 35mm print in existence, which he travels with for screenings. But it's easily found on dvd, and highly recommended.
