Knowing/YMMV


 * Alternate Character Interpretation: Given that the Strangers mentally abuse a young girl, repeatedly stalk and adbuct children, one could make the case their behaviour actually resembles paedophilia.
 * Angst? What Angst?: Abby seems to take the death of her mother remarkably well, when she was only killed while trying to save her daughter from a situation that was caused by the Strangers. This is also completely at odds with their claim that the Strangers "don't want to hurt us".
 * Esoteric Happy Ending
 * High Octane Nightmare Fuel:
 * The disasters we witness, plus a few dreams. For example, the plane crash. Most films go for the flashy initial crash; this film actually bothered to show the immediate aftermath of such an event: Passengers screaming from inside the wreckage, people running, people on fire, people just walking in shock. One shot had a bunch of people running from the plane, you think they're safe, then BOOM!! they're enveloped in flames.
 * This is capped by the final disaster -
 * The vision the alien shows Caleb of  Holy freaking hell.
 * Plot Hole:
 * The point was to show that  This way the first girl at the start of the movie is not the only one with the numbers. And thus several people would learn about the numbers, realize that  and parents will be OK with . This troper is making a large assumption about this based on the fact that we see several space ships leaving at the end.
 * Double plot hole since
 * Was Cage's character the only person on earth to ever figure out the purpose of the numbers? Because otherwise someone else would have told the media and easily proven that the numbers were true and become a famous billionaire.
 * What was the point of giving Lucinda the vision in the first place? If she was one of the chosen ones to be saved, why did the Strangers drive her so insane that she eventually killed herself?
 * Paranoia Fuel: The people shaped things watching the kids. Never mind what they're supposed to symbolize; they are creepy!
 * Shocking Swerve:
 * Although.
 * Tear Jerker: Many, lots. Especially near the ending.
 * Toy Ship: Caleb and Abby.
