Red Christmas is a holiday-set slasher film from Australian director Craig Anderson. Anderson is obviously going for a bit of a Dario Argento giallo aesthetic, with the film's lighting consisting primarily of red and green hues. Dee Wallace (The Howling) is the only real recognizable name in the cast, though the film does feature a standout performance by Gerard O’Dwyer, an actor with Down's Syndrome, who plays Diane's son Jerry.
Red Christmas is indeed a very stylistic slasher film, with Cletus killing off the family members in many creative and gory ways, including being cut in half with an axe, getting a bear trap to the head, or getting stabbed in the head with an umbrella. Even though he's the antagonist, Cletus ends up being the most sympathetic character, especially after his backstory is revealed. While the film doesn't have too much substance to match its style, Red Christmas is a slasher film that should satisfy the gorehounds.
