Jake Cole’s review published on Letterboxd:
Joins the ranks of Ringu and Pontypool as works of horror that capture the horror of "going viral" without risking the immediately dated lameness of actually using the internet. Seimetz's use of negative space not as a means of setting up jump scares but of emphasizing isolation and terror emanating off of characters recalls the carefully composed, simultaneously huge and cramped shots of Rosemary's Baby, and the actors wonderfully capture the pressures of being the unpaid therapists of loved ones going through it while being subject to picking up the same overwhelming dread. Surprisingly funny and even touching at times, though the film never dips into sentimentality. Also, where the hell has Kate Lyn Sheil been? We're getting another shot to make her a star, folks. Let's not fuck it up this time.
