The original Carrie horror movie.

[Brian37]

And that was one point that bugged me about the adaptation: in the novel, her death was a bit different. In it, she uses telekinesis to slow her mother's heart. And you know how the death went in the film. Besides the fact that DePalma decided to create a parallel with St. Sebastian, which, while it might make sense for Brian DePalma (an Italian-American who likely has a working knowledge of Catholicism), does not make sense for Margaret White, who is (at least in the book), not only a Fundamentalist Christian (which, as anyone who's read a Chick Tract knows, has severe issues with Catholicism), but is one whose views are so bizarre that she and her late husband had to create their own denomination that was extreme enough for them, it was apparently changed for budgetary reasons. Somehow, the special effects that made this big sequence possible were less expensive than something that I'm 99.44% certain could be done ON A MINIMALIST STAGE WITH NO PROPS WHATSOEVER.

You have a far deeper working knowledge of this film than I do.

But between the bullies the Carrie character had in the movie and the abusive insane mother in that movie, the mother in that movie is actually worse than the bullies. A parent's job is to protect their child, but while the mother in the movie claimed to be doing as such, she was a psycho. 

At least with Carrie's classmates, most of them, accepted what they did to her was wrong. Carrie's mother simply could not accept her daughter was not a clone of her.
