You had me at “80s-inspired, time-traveling slasher.” I loved Kiernan Shipka in Sabrina, and it’s clear she’s got a long career in horror ahead of her if she wants it. Totally Killer has some great slasher moments, and while the jokes are sometimes a little too on the nose, the pace is brisk enough that there’s not a lot of time to dwell on what hits and what misses. Overall it’s a really fun time-traveling slasher story that pays homage to horror’s best era while being more entertaining than a lot of current horror flicks. Totally Killer succeeds in its mission, and has a blast doing it. I could see this making the yearly October watch list.
