The Darkest Hour begins like a Hostel sequel, with two pairs of Ugly Americans (including Into the Wild’s Emile Hirsch and Juno BFF Olivia Thirlby) meeting at the hottest club in Moscow. Then the lights go out, the sky starts falling, and suddenly we’re watching an extra-cheesy 3D remake of Brad Anderson’s plenty-cheesy-as-it-is Vanishing on 7th Street. Instead of an invisible menace, we get glowing, semi-visible space phantoms that burn you into a cloud of ash. Great care has been taken to transform Moscow into a deserted urban wasteland. That effort might have been better expended on lending the survivors a glimmer of personality – or distinguishing this aftermath-of-the-invasion snoozer from the various sci-fi movies it unfavourably recalls.
