A unique concept alone is not enough

Rating: 5/10 (28 May 2019)

Just one thing, please stop rating decent movies with 1 star or 10 stars.
1 star should be for the worst b-movie flicks with an amateur cast and nearly no budget. 10 stars on the other hand should be reserved for milestones of cinematographic art like Shawshank Redemption and The Godfather.
Now to the movie "A Quiet Place". Emily Blunt and John Krasinski make for a strong main cast as the parents of 3 children in a post apocalyptic world. The majority of humanity has been eliminated by a predator alienrace or demons.
The main premise of this movie is that those aliens/demons rely on their extremely sharp sense of hearing. They can not see or smell. This builds up a strong tension of despair and danger, since every noise could attract the predators and spell demise for the family. The whole concept is very innovative and brings fresh air into the horror genre.
The CGI of the Aliens/demons was decent and also the chemistry in the family.
Unfortunately the movie has too many plotholes and is inconsistent. I think in every Sci-Fi or Fantasy movie, the universe which the story takes its place should be conclusive. Long list of plot holes :
The parents are portrayed as caring. Yet they let their 5 year old son walk 40 meters behind them on a hike, at the end of their line, so he gets killed as first victim by the aliens. Brutal, why the 5 year old son?
On another occasion they let their 15 year old daughter stroll away to the grave of the son, dozens of miles away from their farm, in the night.
They 10 year old other son is sent on a disraction mission to launch some fireworks to distract the aliens, again alone.
They introduce to the viewer that there are other survivors out there, by showing bonfires in the distance. Yet they never develop this string.
The only other survivor is a grandpa who just lost his wife, he must be a neighbour and since they live over a year now in this area, they must have known him. Yet he decides to betray them, by screaming in pain, just when father and son come along. Nice neighbour.
The mysterious house they pass along, another introduced and unused element.
They live in the middle of a cropfield, their house has lots of stored food. Yet father and son decide to go fish hunting while the mother is about to give birth. Seems unreasonable.
The depicted alien race unfortunately could never have reached the earht via interstellar travel. They are better predators, compareable to maybe jaguars or bears. They lack any signs of intelligence, besides primal instincts.
Those aliens could have been defeated by a an ancient army with spears and bows alone. I mean, if a 15 year old teenage girl and her mother who just gave birth can defeat one with a mere shotgun, it is hard to imagine that the combined military forces of modern humanity got wiped out by those basic predators.
The aliens can hear a lamp falling from miles away, yet they are unable to track running kids and heavy breathing from a meter away.
The death of the father was staged and unnecessary to add drama.
The nail in the stairs was hilarious. Not even caveman would have put a nail with the tip upside in the middle of a plank. It is literally in the middle of a blank stairway and it points upside.
Why do they still have electricity even 1 year after the end of civilization? A generator? Generators are loud and need fuel.
1 single man cultivates and harvests this huge field of crops without machines?
The plot with the hearing device made no sense, why should the father make so many hearing devices for his deaf daughter. They barely speak anyway and use sign language.
It is a cool feature that they add real sign language into the movie. Unfortunately the majority of us are not deaf. So we have no idea what they communicate with their hands. Please add subtitle.
The parents decide to make another baby. If you plan to bring another human into this hostile world and endanger your whole family, please prepare your refugium better. An open house with no door and a dirty old mattress as noise isolation seems irresponsible. If babies can do anything well, it would be making noise.
Hard to imagine that the most brilliant scientists could not figure out that the aliens are weak to high pitched frequencies, when even a 15 year old girl stumbles over this solution by accident.
The alien opens up his head all the time in the movie, just to show off the cool CGI. Not only when confronted with high pitched noises, so the conclusion of its weakness is a failure.
