Empire concludes, "The best zombie-ish apocalypse in years. ... it’s the dense social commentary and moral dilemmas that will haunt you." io9 says, "The Girl With All The Gifts is an interesting reflection on what it means to resist, survive, and ultimately thrive in a (real) world infested with rabid, horrifying monsters."
Roger Ebert's site says,
Just when you thought the zombie genre was out of ideas, along comes Colm McCarthy’s smart and engaging “The Girl with All the Gifts,” a film with echoes of George A. Romero, Danny Boyle, and Robert Kirkman but one that also feels confidently its own creation, a unique take on responsibility, adulthood, and a new chapter in evolution.Rotten Tomatoes has a critics consensus score of 86%.
