We pick up this story 90 days after aliens have landed, and boy do they want you to turn that racket down. Anything above a whisper is met with giant, unstoppable creatures wiping you out. The blind aliens’ supersonic hearing is able to discern annoying children from seemingly miles away, and the protagonists that make up the family are rife with annoying kids. The youngest, a devilish child hell-bent on destroying the family, nearly gets them all killed twice in the first ten minutes before becoming a bloody smear on the trail. While no one is looking he puts batteries in a toy that makes noise. You’d think the parents of such an ingrate wouldn’t let him lag behind and do his own thing, but there they are walking obliviously in the front of the pack together.

From this point forward it’s basically a constant reminder to the kids that they shouldn’t be making noise. Generally, right after they were making noise. I believe half the movie is just the parents shushing them.
