Trey Edward Shults’ follow-up to his fantastic Krisha (2015) is less a horror film (as it has been advertised) and more a stripped-down survival story, following the unsteady dynamics of two families sharing an isolated home during a mysterious, unexplained epidemic. Shults slightly changes the film’s aspect ratio whenever the young Travis (Kelvin Harrison Jr.) has a foreboding dream; later, the writer-director alters this pattern in order to blur the line between reality and nightmare. Otherwise, the aural and visual experimentalism that made his first feature feel so exhilarating are largely absent. The performances, though effective, often feel stiflingly muted.
