Almost 10 years later I can see the stylistic traces from these mid-2010s horror films that would very soon be subsumed into "elevated horror". But this still, um, rises above that tag from its sense of propulsive narrative momentum and Eggers' commitment to the time period that renders his style as immersively genuine. Plus the film's particular rising intensity remains transfixing and freaky to me after all these years. 8/10
