too many glaring plot holes to enjoy

Rating: 1/10 (25 March 2019)

I usually enjoy movies without thinking too critically about any plot holes or questionable logic used. However, this movie had me complaining so early about the questionable decision making that I couldn't enjoy the rest of the movie. As I learned more about how the monsters operate, which the characters already knew throughout, I kept asking why they didn't do this or that to completely negate the various problems that the characters were encountering.
One of the biggest issues was the fact that the family knew that by being near a waterfall would drown out noise they make, so why not set up a camp near the waterfall and not have to worry about being obsessively quiet at a farm house. I'll give some slack on the questionable decision of getting pregnant knowing the potential risks birth and a new born would have on the whole family (could've been unplanned etc..), but why didn't they at least move to the waterfall when the baby was close to birth, so they'd be prepared for the mother and child's noise. Or even put some effort ahead of time sound proofing a room in their house. There was even a calendar on the wall showing the expected birth date, so its not like the birth came out of nowhere. Very basic planning ahead could have made her giving birth a less suspenseful and life threatening (getting killed by monster) event.
Plus there are many other issues I have with this movie that other reviewers have already pointed out, so I wont rehash those, but the waterfall issue was the biggest I had since they make a point of how safe it was to shout and yell safely by the water. So in the end I couldn't get over that fact the rest of the movie and so it made it a disappointing attempt at an interesting concept.
