This essay by Mike Flanagan on his favorite horror movie is one of several contributed as part of Variety’s 100 Best Horror Movies of All Time package . When I find myself talking to someone familiar with Joel Anderson’s 2008 film (which isn’t often; it remains criminally underseen), our eyes usually go wide, our pitches rise and soon we’re giddily gesturing and speaking in half-thoughts like two people who share a great secret.

Alice’s story is not a simple one, and there are several surprises along the way that make you question what you’ve seen — but it all culminates in one of the most horrifying and devastating moments in horror history. It’s a moment that, on my first viewing, made me leap involuntarily from my couch and pace in my living room.
