Really, how slovenly is it to use invisible aliens? If you're going to tease us with nothing but pinwheels of light for three-quarters of the film, you'd better have one heck of a reveal up your sleeve.
The Darkest Hour is a science-fiction film starring Emilie Hirsch, Olivia Thirlby, Max Minghella, Rachael Taylor, and Joel Kinnaman as five people who are fighting off a species of aliens who attack them while in Moscow. And, I know you're thinking that this sounds kind of dumb and unoriginal. Well, what were you expecting? There were many missed opportunities with The Darkest Hour. Not only was this venture unsuccessful, but it's also uninteresting, and has some pretty awful acting.
