The creatures in this have to be almost Signs level nonsensical, right? Signs at least played a very long build up to their arrival. Wouldn't all the noise and radio frequencies of the modern world render these creatures pretty much incapacitated? Just the noise of average city life would be a cacophony so great it would completely disorient them. If it was contained to just this rural area it would be fine, but the movie makes out like these creatures have wiped out most of human civilization.
