What did the aliens want? (Spoilers)
It was never really clear. Just to kill an earth family and then go on their way? Kind of like an interstellar drive-by shooting? We never really find out anything at all about the aliens. I suspect they were supposed to be scary, but, to me, they were just too far out there. I couldn't tell whether they were coming or going. Things based on reality are, of course, much scarier, as any good horror filmmaker knows. You get far enough from reality and things just start looking silly.
And what was with the subplot about the water reservoir, with the mayor and all of that?
I began thinking the film was maybe supposed to be some kind of allegory about pollution or something. Dunno. I'm grasping at straws.
Can anyone give me a hand here?
