A risky genre-bender that brings the story's central question back in the end to the viewer to answer, it's a rare film that dares this somersault. What do I mean? Commercial narrative movies mostly plot a storyline that ultimately plays to the expectation to entertain. Rarely does a film slap us in the end to wake up out of the trance of watching a movie and re-think what we've seen. Like the Schrodinger cat experiment, we'll only know the answer if we open the box, but the film only leads us to the box. Sometimes that's a gimmick, but given the subject matter, here it's a clever device to get us to rethink everything and reconsider the crucial question of the story. Of course it will alienate many viewers who will watch it because of the "thriller" and "sci-fi" taglines, since it uses the genre formulas only as disguise. Cinematically, it's well done, playing around with standard movie tropes and conventions and crossing some lines but not going overboard. It's a shame Peter Scanavino settled for Law and Order. Based on this performance he could've done much more. Jason Robards III is eerily reminiscent of his late father and David Thornton is brilliant. Why aren't they more present in mainstream movies? Bottom line, recommended if you're up for a subversive cinematic experiment in form and content.
