Written and directed by Terrence Malick protégé Trey Edward Shults, It Comes at Night (B+) is a superb psychological horror film that wrings generous art house thrills out of a straightforward apocalyptic premise. A couple and their son (Joel Edgerton, Carmen Ejogo and Kelvin Harrison, Jr.) have secluded themselves in a country home as a contagious disease plagues the outside world, and they are faced with a cat and mouse dilemma when visited by another couple and their son (Christopher Abbott, Riley Keough and Griffin Robert Faulkner) who may or may not be safe or worth harboring. Edgerton and Abbott are fabulous foils, one the rule-abiding master of an elaborate isolated house and the other the scallywag with a backstory. The casting is creative and unexpected: Abbott is wonderful, and the acting is great all around. Shults makes the most of a fairly low-budget bare-bones production space to stage his wicked one-upmanship. He is imaginative in what he doesn’t show the audience and teases with darkness as an effective canvas for scares in the first act before introducing a more conventional narrative. Hardcore horror fans may be let down by the lack of gore and by the calculated pace, but this summer film-goer was delighted at the effective storytelling on display.
