You know, you piss off the wrong person at a high school dance and you just never know what might happen. Remember what happened to all those kids at Carrie's school after they laughed at her all covered in pig's blood up there on the auditorium stage? Well, that was in 1976 when Sissy Spacek
played Carrie and was nominated for an Academy Award for her efforts (as was co-star Piper Laurie
in the Best Supporting Actress category).
Now Carrie's back and those amazing telekinetic powers she has are probably a little rusty from underuse -- but I wouldn't make fun of her if I were you.
Based on characters created by Stephen King in his novel of the same name.
