For his first two features, writer Michael Kennedy has used essentially the same strategy. He takes an iconic movie plot and asks, but what if it was a slasher? There’s 2020’s Freaky Friday riff, Freaky, and now he teams up with Tragedy Girls director Tyler MacIntyre for It’s a Wonderful Knife. You can probably discern the premise from the title. The result plays something like an unapologetically queer Hallmark Christmas movie covered in blood and stab wounds. Which is as much damn fun as it sounds.
