Is a pretty predictable story except for the part that she kills most of the town...
Carrie was a bullied girl, a victim with no friends and a religious fanatical mother. She didn't know about her telepathic powers because that was subtracted from her memory via punishment and what I would like to think was a brain wash.
The story is based on abuse, bullying, revenge, fear. Obviously not a happy ending type of story, not that I was expecting that.
For me is a 3 stars ⭐️, because it was so predictable, maybe that was the intention.
