It was raining on Saturday, so I went to the cinema to watch Backrooms. For the uninitiated, this film grew from a creepypasta story about a haunted furniture store into a multifaceted piece of internet lore. Think an endless sequence of windowless rooms inhabited by unknown dangers. Think House of Leaves, liminal space, the uncanny, and David Lynch.

Now the film is, as they say, a major motion picture. It is also the most terrifying film I have ever seen.
