"The film begins with a quote by author Arthur C. Clarke: "Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying." Dark Skies addresses both sides of the coin as the family tries to determine if the strange occurrences they're experiencing are due to mental illness, or if they're being visited... Science fiction is often about the mystery, the unknown. That aspect of the film, for the most part, is removed. The horror element, on the other hand, still strives. It subtly shifts from unsettling to effectively employing jump scares." - Sarah Gopaul, Digital Journal
