Not a solid movie

Rating: 6/10 (6 July 2018)

I like the idea of having to be quiet in order not to attract the videogame monsters.
However, it isn't really realistic in any sense. What are these creatures? Are they aliens? If so, how did they even build anything in order to get to earth?
Or are they monsters released by more highly evolved aliens, if so, why don't they for instance map out the human DNA and release tons of diseases in order to wipe us out? (hint: here's a new idea. They don't even have to wage wars against us)
Since the monsters cannot hear when close to a waterfall, why not create soundtraps with loudspeakers? If things go wrong make sure to make the noise elsewhere. And since the monsters do not seem to make use of their sense of smell why not simply move from the source of noise and stay fully quiet? Or, bring something with you that you can throw to decently great distances which makes noise so the CGI monster seek for the food elsewhere?
The kid could have thrown away the noise toy and have actually been safe.
Who delivered the newspapers?
Why do they not go to other neighbors with fires on at night to team up?
What do they know? What resources do they have? Can they go to an island somewhere which has no monsters?
Why a fourth child when you cannot even keep track of the other three?
And since it so easy to understand that they go to noise, they would be fantastically easy to deal with the help of a military who simply put on loudspeakers and target them with heavier weapons. So, this is not Aliens or Life, where the monsters actually have some intelligence and thought behind it / them.
Still, it's an OK movie, and this is thanks mostly due to the above average acting.
Watch instead: Don't breathe
