Suspenseful and engaging but full of ridiculoous plot holes

Rating: 6/10 (20 July 2018)

I wanted to really like this, but especially after seeing it a couple of times and the more I think about it, it has too many fails to be a hearty recommendation. It expects the audience to accept way too many contrived problems and just wasn't very smartly designed...perhaps intended for a young/naÃ¯ve audience; even basic skepticism needs to be set aside. If I didn't know who the writer/director was, I'd guess this was an M. Night Shyamalan production (not exactly a compliment).
Spoilers below...
Examples abound, like the nail in the stairwell (seriously, how is that even a thing? Anywhere?), the creatures' incredibly sensitive hearing yet unable to hear someone breathing in the same room, how they happened to know that there were only 3 creatures in the area, the creatures being relatively easy to kill with conventional weapons yet managing to become Earth's alpha predator (like...plant a super-loud speaker system somewhere to corral and blow them all up), why the main family wouldn't live right by the river for sound masking, how they managed to launder their clothes w/o making noise, how they would risk the entire family by allowing the chance of conceiving another child, how they would let the little boy be the last one to leave the store and trail so far behind while knowing how unreliable he was, how one creature making noise didn't draw others to the area, and on and on...
Nice try.
