Silent Night, Deadly Night 5: The Toy Maker (1992)

"Joe Petto is a toy maker and his son Pino lives with him but Joe wants a real boy and Pino is getting jealous. Do I have to really give you anymore of a plot? Gepetto and Pinocchio? And murder at X-mas? Pino gets jealous that Joe wants a real son and well you get the point. Utter blah on this end and how desperate is Mickey Rooney?" - Rich Wolf of Obscure Horror

Santa's Slay (2005)

"Meanwhile, Santa visits a strip club where the town preacher is at. We get multiple boobie shots while Santa kills all the guys in the place, then he eventually burns the place down to the ground, killing all the strippers with unique names like Kandy Kane..."
- Jason Soto of Invasion of the B-Movies

Silent Night Deadly Night Part 2 (1987)

"When your headlining killer's biggest contribution to the Mad Slasher world is the creation of an awkward Internet meme ('GarBAGE Day!!!'), suffice it to say there's not much hope that he's going to be all that threatening. He's more like a Saturday Night Live character they introduce at about the 1:00 AM mark."

Christmas Evil (1980)

"During his mad excursion he drops by a hospital to unload more gifts and then kills some people outside a church with a hand axe. Then he crashes a party, gives out more gifts to kids and dances for awhile. I can’t explain how creepy Harry can get, it’s as if he was drunk on madness and managed to keep himself from killing even more people, for the sake of the children." - Jorge A. Lopez of Strictly Splatter

Silent Night, Deadly Night (1984)

"One Christmas eve, Billy, who is around 6 years old and his baby brother Ricky, who is 6 months old, watch as their parents are raped and killed by a drunken thief in a Santa Claus outfit. They end up in an orphanage where they see a nun have sex. Then Billy grows up into an awkward muscle-bound goon." 
- Jose Prendes of Strictly Splatter

Black Christmas (2006)

"We learn that Billy killed his whole family in spectacular fashion one Christmas Eve many moons ago, and he tries to escape from the asylum every Christmas so he can return home. Will this be the year Billy successfully escapes? Is his home now the sorority house we saw in the opening? Do you really need me to answer these questions?"
