But I genuinely want to know what people think is the best horror movie of the past decade. I know "best" is vague, but trust your gut. Because for me, the scariest horror movie isn't always my favourite or the one I'd call the best. So here's how it works: I'll show you two movies at a time, and you have to pick which one you think is better. Then the winners will keep facing off until you're left with your final choice.
