Illogical... Flawed and quite stupid.

Rating: 2/10 (7 April 2018)

Spoiler alert...
Don't read before watching... Or read if not planning to watch... I'd recommend the second option...
The family knows that higher sound levels will hide the lower sounds... And the father actually showed the son how they can yell and shout beside a waterfall...
Any sane group of people would immediately think... Hey... What a wonderful place to live at... We can talk and do normal things as long as the waterfall sound can mask it...
The father has a whole range of electronics and showed he knows how to make them work...
Maybe it's just me... But I'd have my fun with the aliens by hooking up a hundred speakers all over the place on top of trees and under rocks etc... and then sit on the silo making each one make a sound alternately... By making some sound on one, then a minute later sound another a few miles away and on and on...the entertainment would be watching the aliens rush to one and then to the other until they run themselves dizzy...
When the entertainment is over... They can all go back to their waterfall home and laugh themselves silly...
If the movie followed this plan... It'd be done in 20 minutes... Assuming the first 15 minutes are needed to set up the story... And even we can only handle watching aliens run around in circles for no more than 2-3 minutes... The last 2 minutes are the family back at their waterfall laughing and joshing about the day's entertainment and eating as loudly as they please...
So there... Was going to give this movie a zero... But I like Emily Blunt in Edge of Tomorrow...so it gets a 2...(in that one, she kicked arse... In this one... Not so much...)
