What seems like a promising homegrown horror turns out to be just another shaky-cam shock-fest. Produced by Hammer, featuring a fine young cast and painted in stylish ’70s hues, it certainly looks the part, with grainy Super 8 stock putting a vintage sheen on a choke of clichés.

There’s creepy dolls, cameras tipped on their side, blasts of white noise and a horny teenage Scooby gang helping Jared Harris’ Oxford prof stir up a poltergeist in the mind of a moody emo girl (Olivia Cooke).

Sam Claflin plays the videographer whose occasionally found foo🌄tage adds bursts of atmosphere❀, but jump-heavy scares numb the nerves long before the finale.
