The withdrawn, bullied teenage girl Carrie would have been in therapy and likely in a foster home until her mother got her parenting skills together. The current film "Carrie" doesn't engage audiences because we are hyper aware how vigilant school systems are about picking up on psychological problems, harassment, and misguided parents.
For example, any female who had not been briefed about her monthly would automatically come under the radar of the school social worker. The mother would have been hauled in. During the interviews with the social worker and others brought into the loop the nutty belief system in the home would have been uncovered.
The story could have ended happily with Carrie working with a sensitive female shrink and coached in social skills by a Big Sister. Instead of imploding she would be on her way to college. There she could have majored in science, math, or engineering. She would have gone to her fifth reunion as an attractive, self-assured woman who was working at a wonderful job.
Those of us who were versions of this fictional Carrie resent projecting her plight into current times. Had I been in the public school system today I might have received the help I needed. Lots of the suffering I subsequently endured could have been prevented.
