History YMMV / BlackChristmas1974

** Peter quits the conservatory after his botched recital, tries to badger Jess into marrying him, and again tries to shame her out of getting an abortion. When Jess refuses, he tells her she'll be sorry and leaves angrily, but is later seen skulking around outside the house after the police leave. [[spoiler: He then breaks into the house again through the basement window, which is when Jess kills him, believing him to be the killer. In light of his abusive nature towards her and his threats, it's not hard to believe that while Jess was mistaken about him being the killer the police are looking for, [[IfICantHaveYou Peter might have breaking back into the house specifically to kill Jess.]]]]

* CultClassic: Considered one of the grandfathers of the slasher genre. Its cult status even gained it [[Film/BlackChristmas2006 two]] [[https://www.imdb.com/title/tt10481868/?ref_=nv_sr_1?ref_=nv_sr_1 remakes]]. Olivia Hussey once had a moment where she met Creator/SteveMartin, who told her she was in one of his favorite films. She assumed he meant her most famous role ''Film/RomeoAndJuliet1968'', but he meant this!

* OnceOriginalNowOverdone: It was, more or less, one of the first slashers -- so the plot points of a killer picking off young women one by one, harrassing them over the phone and an obvious FinalGirl can feel a bit formulaic. Despite all of those things becoming staples of the genre, various examples of UnbuildTrope work in its favour, retaining ''some'' of its originaity.

* SeinfeldIsUnfunny: It was, more or less, one of the first slashers -- so the plot points of a killer picking off young women one by one, harrassing them over the phone and an obvious FinalGirl can feel a bit formulaic. But it is argued that Bob Clark's direction, the refreshing nature of the characters (see below) and a lack of gratuitous sex mean the film still holds up quite well.
