‘Backrooms’ movie review: Kane Parsons’ postmodern labyrinth is a mesmerising moodboard for the horrors of the internet age

When I was a child, the nightmares that terrified me the most seldom involved ghosts, killers, demons, or any other entity desperate for screentime during my dream time. It almost always involved just a place. This was always a familiar place, yet somehow uncanny. It often felt oddly serene, but had a malice of some sort that seemed woven into the space itself. There was something off about it that triggered a fear so primal that I’d often wake up in a cold sweat. Sometimes that dread would take shape as some vague, menacing thing pursuing me with unspecified intent and relentless determination. Most of the time, though, the place itself was enough. But to know it, you must first have dreamt it.
