After all the Halloween-based horror movie viewing, I suggest you change gears to winter and Christmas-themed ones. Here's just some -
Silent Night, Bloody Night (1974) A man comes inherits a mansion that was once a mental home and begins to investigate some murders there, upsetting the locals. This was by some considered to be the first of the slasher films genre. It is extremely moody and dark and I consider it to be a classic.
Krampus Origins (2018) The first World War rages on when a group of American soldiers find a mysterious artifact that can summon the ancient evil of the Krampus. After the men are killed in action, the artifact is sent to the commanding officer's widow who is a teacher at a small-town orphanage. The orphans accidentally summon the Krampus and the teacher, and her pupils are forced to battle this ancient evil.
Christmas Evil (aka, You Better Watch Out, 1980) Dark comedic horror about a boy who learns Santa isn’t real and then goes on to become obsessed as a toymaker, only to snap and beginning a killing spree.
Don’t Open Until Christmas (1984) Someone donning a Santa suit is going around London killing people during the holiday time.
Santa Claws (1996) A crazy guy who kills his mother and Santa (when she's making love to a man in a Santa hat), grows up to become obsessed with a porn star and begins to dress like Santa and kill people with a claw.
Gremlins (1984) A boy gets a cool new pet for Christmas only to break the special rules that come with it, resulting in a town torn apart by marauding creatures. This is total tongue-in-cheek but fun.
To All a Good Night (1980) A group of partying teens are attacked by a man in a Santa suit.
Black Christmas (1974) Girls left behind in their sorority house before Christmas Day are being tormented and killed off one by one by a psycho hiding in their house. There is a newer version of this movie, but I highly recommend this well done original. It’s much more suspenseful and has some big name actors and more mood. This is a classic and my favorite of the Christmas horror stories.
Jack Frost (1996) A serial killer dies and comes back as a maniacal killing snowman.
Santa’s Slay (2005) Santa is a demon who does his time giving toys, but when his deal is over, he goes back to his naughty ways.
"Krampus" (2015) A boy who has a bad Christmas ends up accidentally summoning a festive demon to his family home.
Others with a winter/snow theme:
“Ghost Story” (1981) With a huge all-star cast and a moody dark atmosphere and ghost story-telling feel, this is ideal for a fireside horror movie. A classic.
”Storm of the Century” (1999) A snowy town is being tormented by a stranger amongst them.
“30 Days of Night” (2007) A town in Alaska has 30 days of night (unfortunately because they also have vampires arriving).
“Frostbiten” (2006) Vampires terrorize a town in Sweden.
“Let the Right One In” (2008) A bullied boy in Sweden makes friends with a neighbor (vampire) girl. This is my favorite vampire movie of all time!
”Phantoms” (1998) A small town in Colorado has hundreds of dead people. What’s killing them and how can they protect themselves?
“The Shining” (1980) A man and his family take care of a remote hotel during the long winter and cabin fever ensues. A classic.
"30 Days of Night" (2007) After an Alaskan town is plunged into darkness for a month, it is attacked by a bloodthirsty gang of vampires.
"Wind Chill" (2007) Two college students share a ride home for the holidays, but when they break down on a deserted stretch of road, they are preyed upon by the ghosts of people who have died there.
Curl up with a fire in the fireplace, make some hot cocoa, and to all a good night.
