Prime Video's Totally Killer pays homage to the slasher horror subgenre and other iconic films. It feels like a crimson take on Back to the Future, with a murderer rocking a whimsical mask while murdering people in two different timelines. In this case, Jamie (Kiernan Shipka from Netflix's Chilling Adventures of Sabrina) has to figure out who killed her mother, Pam, in the present by unmasking the villain in 1987 on Halloween night.
