Headscratchers / Skyline

• It would have all been for naught in the end, but still not one of these people suggested or thought of staying in the hall or a room without windows (they could have taken that TV connected to the telescope to see outside from safety), or getting supplies from the other apartments (like when they say they don't have enough bedsheets to cover the windows). They also don't bother attempting to manually lower the electric shades.
• There's got to be some seriously diminishing returns for those aliens. I mean, it takes power to run anything and it costs maintenance and resources to have your collectors go door to door in every building in every city on Earth. Particularly when you realize that plenty of them are going to be damaged or destroyed once the element of surprise is lost. Weren't the first 5.5 billion humans enough? Do they really need to scrounge around for each and every one?
  • I think they were trying to free humanity of organic bodies, they just didn't care that we didn't want this to happen. The aliens were the good guys.
    • Compared to most of the lead cast, this statement is painfully true.
    • Except for the stealth bomber. He was the best
• If their ships can withstand a nuclear explosion directly against the hull (10 million degrees Celsius, or the temperature halfway to the core of the sun) then they shouldn't have even bothered launching fighters. Further away from the heart of the blast it would "only" be 10,000C, which is at least somewhat plausible to survive. Unless every surface on the inside of their ships is as strong as the outside, then when the 10 million degree heat vaporized that part of the hull and the hurricane-force sun wind poured in, the result should have been exactly what you'd expect to happen.
  • It doesn't help that the ships appear to be made of random bits of garbage ripped out from the ground. A stiff breeze should make them crumble, let alone a direct hit with a nuke.
  • ...their ships CAN'T withstand a direct hit from a nuke against their hull. The ship the nuke hit was completely destroyed. The problem with machines is that they can be reconstructed, good as new, given enough time and resources, which is exactly that's what happened with the nuked ship.
  • Just because a ship CAN withstand the blast doesn't mean it's not an extreme waste of time and energy rebuilding. An ounce of prevention is worth a pound of cure.
  • It wasn't completely destroyed. The ship just fell to the ground in a burning, but largely intact, wreck. Hitting the ground seemed to cause more damage than when the nuke hit. There shouldn't have been enough left of that ship to repair.
• If the ship is supposed to have an organic "core" of some sort - having DNA, according to Word of God - I can't imagine the megadose of nuclear radiation it took when getting hit will be beneficial in the long run. Lot of the brains probably pretty radioactive, too.
