Writer-director David Robert Mitchell has delivered a film that’s unabashedly Amblin but more J.J. Abrams-core Amblin, à la Super 8 (which was not only stylistically informed but also backed by Amblin and hands-on produced by Spielberg, the company’s founder). For worse, David Robert Mitchell had proven himself a relative renegade in the industry with his first two theatrically distributed, totally unalike features—It Follows and Under the Silver Lake—and one can’t help wondering why we’re suddenly getting something from him that’s so recognizably something else: Amblin, be it the Spielberg, Abrams, Goonies, or Jumanji brand.
