The film: Carrie (1976)
The death: Picking up the prom-queen prize, telekinetic teen Carrie White (Sissy Spacek) suffers a serious sense-of-humour failure when prankster John Travolta dumps a bucket of pig's blood over her.
She uses her special think-powers to burn down the school and kill most of her peers, before running home to her mentalist bible-bashing momma who stabs her.
The revenge: After the mayhem, Carrie's classmate Susan drifts in to the cemetery and, to woozy visuals and lilting music, places flowers on Carrie's grave...
Best revenge moment: AAAAAAAAAAAAAAAAAAAAAARRRRRRGH!
