It's like two totally unrelated films happening at once. The story that is initially set up (the disappearance of Maisie) was a ten minute story dragged out with uncomfortably long slow mo and an hour and half interval to watch some lights flickering. I had worked out whodunnit in the first five mins and can't believe I wasted my time thinking perhaps something interesting might happen, especially when the aliens rocked up. There's lots of influence from other films (Space Odyssey / Signs / War of the Worlds / Close Encounters) but as there's no story here, I wished I'd have just rewatched one of them instead. The acting was OK but it's not like there was much going on, just standing and staring mainly.
