The “Scary Movie” franchise does such an effective job of mocking horror movie conventions, it’s hard to watch “The Dead Don’t Die” (2019) and feel like you haven’t heard these jokes before, because in some cases, you have. Adam Driver and Bill Murray are small-town cops confronted with a slow-motion zombie apocalypse. That’s because zombies walk slow (which is the kind of gag you might see in this movie) but also because the story kind of drags, like a corpse’s partially severed limb. It’s very close to being hilarious (especially Tilda Swinton’s scenes), but ends up too clever by half.
