A YouTube sensation just crashed the A24 party. Kane Parsons, the viral video creator, delivers his feature film debut, 'Backrooms,' to critical buzz. Variety calls it an 'experimental horror' masterclass, praising Parsons' Lynchian grip on mood and sound. Scripted by Will Soodik, the film reportedly wrings genuine terror from its enclosed, infinite serial killer's lair aesthetic. Is this the next big horror voice, or just a head trip?
