The Darkest Hour is still a stinking pile of crap that is barely watchable thanks to Emile Hirsch. Everything else seems rushed, half-baked and copied from another shitty sci-fi film. Alien invaders have never looked so invisible and harmless before. Watching The Darkest Hour is a guaranteed headache inducer that’ll have you pulling your hair out by the end credits."
