Suspenseful and entertaining but some plot points lacking

Rating: 7/10 (9 April 2018)

Enjoyed the movie for the most part and the creepiness and suspense was definitely the highlight. The first half of the movie all in silence adds to the tension, the main protagonist couple loses a small child in the beginning to terrifying unknown creatures because the daughter gives him a toy that the father specifically told him he could not have. That is a necessary plot point albeit ignorance and disrespect of the daughter and the small child knowing the consequences of making noise which is what the toy was designed to do. Fast forward to the family living in silence, the mother is pregnant ,another plot point that comes into play later in the movie, babies make a lot of noise so not smart ,most likely they wanted a child to replace the lost one. The writers added these plot points that make it more tense but in reality why would you want to bring a child into such a terrifying place and one where the baby's normal noises would risk lives . Of course they build a soundproof shelter under the house complete with a small chamber with air to keep the baby's noises hidden . Why didn't they just go in that soundproof area to talk to each other in the first place and not have the tense moments avoiding knocking things over accidentally which does eventually happen. A lot of these plot point made no sense and more than likely added to create more tensions and scary moments. Such as they already know the creatures track by even the slightest sound, so why wouldnt a plot point involve more ways to distract them , since they are sound sensitive I'm sure someone in the billions of people could exploit that weakness with high frequency sound and other ways to incapacitate them.
It's not really explained where the creatures came from ,we only see glimpses of the newspaper clipping the father has saved about a meteorite landing which brings the assumption they are aliens and that they have virtually indestructible armor plating ,even to nukes? i mean you could dig large deep pits and lure them in with sound devices like the egg timer the wife has or fireworks like the son uses later on and trap them - then try gassing them or something else , they have to breathe so why not . Well, its a movie so certain reasonable plot points make no sense , the ignorance of the children especially the deaf daughter which causes the father to lose his life . That in itself is a rather stupid scene of self sacrifice. And the signal fires they light at night , the creatures relay on sound and are blind but can they smell ? And we only see 1 other human character ,an old man who dies after his wife is killed . Where are the other people lighting the other fires we see early in the film, later in the film the kids light another fire but we do not see the other fires anymore . Does this mean the other people who lit them before are dead? . There are plot holes of course as to why there are no other people seen besides the family and the old man? Did the military get over run by these creatures? If this random deaf girl discovered how to use feedback from her hearing aid to fight the sound sensitive creatures , wouldnt someone far more intelligent like a scientist have found that out ? Such things make the movie less plausible and more on the suspend belief category .Yes it's fictional but sometimes it would be nice if the writers threw in some common sense and not way too many inconsistencies.
