"While it is mostly devoid of dialogue, it is a film rich in subtle textural detail. From the sand-strewn paths on which the family carefully tread to their simple white-light/red-light warning system, the visual tapestry of their everyday life is a constant reminder of how they cope with their predicament... despite its well-played jump scares, it operates at a deep emotional level. Aside from the fleeting appearance of an ill-fated elderly couple, there are no other human characters on screen; this apocalyptic tale is told entirely through the prism of a single family, one struggling to cope not only with actual monsters, but also with insidious personal demons of grief, blame and guilt." - Nikki Baughan, Sight & Sound
