Let´s be blind to the none sense

Rating: 5/10 (4 May 2020)

My first problem with this film is that it doesn´t set how sensitive the aliens are to the noise. As everything makes noise (breathing, heart beating), if they can hear ultra sounds, this family should never have survived. But let´s say that in that case, there would be no film.
Moving to the first scene where the kid is getting killed because he is playing with his toy, why are the parents walking so far ahead of him, apart so we can see the action of the father running to him?
Then they arrive at a fountain so loud that we are explained that they can speak as they are covered by the noise. So the aliens are not sensitive to all noises, only the loudest one. So why not being loud all the time from different places so the aliens don´t know where to attack first?
Finally, I understand that the lead actors are the glamour hollywood couple of the moment and we are all very happy for them and to see them in a fake family with a child bearing but why did they decide to have another child in this impossible world?
These are the absurdities I took notes of during the first 40 minutes but it goes on.
The reason why I am still rating it 5 is because the script is original, the acting is technically good and the direction keeping the action ongoing.
If you put aside the none sense of most scenes, you may enjoy it. If like me you expected the story to be consistent with the plot, you may be disappointed.
