I am speechless ... at how others can give this film 9 and 10 stars

Rating: 4/10 (7 April 2018)

This film is a classic case of "we just have to make a film about that premise", however what the people involved didn't do well is figure out how to cover all the plot holes the premise was always going to introduce.
The introduction is moving and sets up the premise well, however I started to realise the lack of care that would be taken later in the film when I realised that I was being asked to believe that a four-year-old (left to walk by himself at the rear of a family in a dangerous situation) could get two batteries inserted in a toy. Even if the kid could do it, the chances would be only one in four of getting the batteries oriented correctly. Why didn't the creature come back to hunt the father based on the sound of his running footsteps?
So it's possible to kill the creatures with a gun? Okay, then ... with gun ownership in the US being about one per capita, surely the creatures would have been wiped out long ago by having provided the population with the target practice they must secretly crave?
So a family with kids survived whatever (unexplained) apocalypse occurred prior to the film's beginning, but the army didn't?
So the creatures have no vision and super-sensitive hearing? What about a sense of smell?
So no one talks in their sleep or snores (or has farts)? Do toilets flush?
So the creatures can rip though a metal grain silo, but not instantly get into a truck to get at the two kids inside? And out of interest, how do you harvest a field of corn without making a sound? How do you remove the kernels of corn from the cobs and get them into the silo?
So they have to play Monopoly with crocheted pieces (to avoid noise), but the sound of a truck rolling down a hillside is okay?
I think that would be shortest labour in history. I'm pretty sure the timeline in the movie is continuous enough to prove that she only had three or four contractions. None of that annoying 30-hour stuff for her!
Would the hearing aid really have broadcast with enough power in the right frequencies to affect the creatures that much? Would those frequencies have been reproduced by the microphone system? Who knows? Perhaps. To be honest, I find the similar resolution based on the playing of Slim Whitman's "Indian Love Call" in the film "Mars Attacks!" to be almost as believable.
Why not spend most of your time living behind the waterfall? Why not set up a remote-control noise maker on the lawn and set up position on the porch with a shotgun? And I'm sure that I'm only scratching the surface when it comes to solutions.
And there were too many horror-movie clichés: intensely irritating sounds at crucial moments and terror originating just outside of shots tightly centered on actors.
The cocking of a shotgun just prior to the credits screams sequel. That really would leave me speechless.
I will say that I thought the actors did a fine job. No problems there. If you want to suspend disbelief entirely and just let horror clichés wash over you for ninety minutes ... this is the film for you.
