Jeffrey Donovan from Blair Witch 2 here plays Jack, who is paired with appealing imp Lu (Quinn McColgan) after a bus attempting to take them to a safe space is attacked by a group of gorily realised zombies. As if events were not punishing enough, the world - or this portion of it - is also in the grip of an unforgiving winter, convincingly directed by Miguel Ángel Vivas, who also co-wrote this.
The locations, filmed in Spain and Hungary, are superbly shot. As the character of Patrick (Matthew Fox) is introduced and the three main players form a fragile triumvirate, 'Extinction' settles into a personal story of the plight of these people we have come to know, against the magnitude of the palpably grim world in which they live, and the rotting living corpses that frequent it.
If that's not the recipe for a good night in with a mug of something warm, I don't know what is! My score is 8 out of 10.
