The Remake of the 1974 slasher filmBlack Christmas, released in 2006.Much like in the original, group of sorority sisters are celebrating Christmas. But the killer who crashes the party has more than a passing familiarity with their house: he used to live there, and he's going to relive the deaths of his parents.
Double Standard: Rape, Female on Male: Averted. Obsessed with having another, better child, Mrs. Lenz, after her lover passes out during a bout of drunken sex, goes up to the attic where she keeps her deformed son Billy, and rapes him, successfully giving birth to a daughter nine months later. Suffice it to say, this contributed greatly to Billy's already steady descent into insanity.
Kick the Dog: Billy's mother crushing the "Baby's First Christmas" bulb, and later telling him that Santa was shot down by the Russians.
Kick the Son of a Bitch: It is immensely satisfying to see Billy getting revenge on his stepfather and mother for all the things they've done to him. The former being impaled through the head with a christmas tree topping and the latter being strangled and brutally beaten to death by a rolling pin.
Kill the Cutie: Melissa, the only main sister besides Kelli who is halfway decent. Leigh is also a decent character, but isn't one of the sisters.
Madwoman in the Attic: Billy's mother despised his father, and by extension him (the fact that he looked like That Yellow Bastard only added to that hatred). She and her lover wound up murdering Mr. Lenz, and kept Billy locked up in the attic, presumably only giving him the bare minimum to survive.
Woobie, Destroyer of Worlds: After witnessing his fathers murder at the hands of his bitch of a mothers jerkass lover, being locked up in the attic for several years and being raped by his mother in order to conceive a child, its no wonder why Billy cracked up and became an axe crazy lunatic.
