Backrooms proves that its analog horror belongs on YouTube, in short form. Once stretched into the sterile, pristine, high-definition renders of a feature film, paired with surface-level psychology (and, worse, clumsily and hollowly overexplained mythology), it loses all potency.
You can have two great actors like the always compelling Reinsve and the powerhouse that is Chiwetel Ejiofor, wandering through labyrinthine, disorienting spaces, and still leave us cold. No dread, no substance, no story. Just atmosphere and setting.
Many will project their own ruminations onto the maze and extract yet another “profound” horror metaphor about trauma, abuse, or identity. But ultimately, it all feels cosmetic rather than psychological. And even then, it's underwhelming.
