Acclaimed Horror Movies That Got Away With Not Explaining Major Things

List Rules
Vote up the plot holes that make the least sense.

Horror movies are often described as a "guilty pleasure" and rarely make a splash when award season comes around, which is really unfair. There are plenty of horror movies that are absolute critical darlings, changing the way we think about fear and the world. There's a big "but" coming, though: Even the best horror films sometimes rely on a kind of dream logic, rather than, you know, logic logic.

Classic horror films really shouldn't be put under the microscope for too long, or else you might start noticing some cracks in the facade. Plot holes, bad logic, and downright absurdity can be found in even the best films. Is your favorite horror movie immune to these plot holes, or is there something important that got left on the cutting room floor?
