Totally Killer (2023) review

Back in 1987, a mask-wearing murderer took out three young ladies on their sixteenth birthday (each with sixteen stab wounds) and was never captured - thirty six years later, he makes his return and kills former classmate Pam Hughes (Julie Bowen) in her own home, so her spunky daughter Jamie (Kiernan Shipka) gets into a photo booth that doubles as a time machine her best friend Amelia (Kelcey Mawema) constructed, travels to the 80's, and tries to warn everyone (naturally, they're less than receptive).  While the setup is a just an uncreative (but self-aware) amalgamation of various other movies (Back to the Future is mentioned, but Wes Craven's Scream is the key source) and neither scary nor all that funny, it is a little interesting to see "progressive" Gen Z (with Kiki as their Ambassador) come into actual contact with their parents' generation, and it clearly remembers how downright mean and crude a lot of people were (this could also apply to the 1990's).  Nothing really checks out on a logical level, but it's not the kind of movie that worries about such things....
