Party of plot holes

Rating: 2/10 (23 April 2018)

This is one of the most overrated horror-movies I´ve ever seen. I went to see it because of the apparently good ratings, which probably has occurred from other places than from viewers. I actually don't know why I didn't leave the cinema.
First, the movie has a lot of plot holes: 1. Why does the family leave the youngest kid behind? 2. Why is the oldest son ill in the beginning? ( I thought it had something to do with the plot itself, but that was apparently not the case). 3. Why doesn´t the family live by the river, which is supposed to be the only safe place? 4. There were bonfires in the forest, why did we never get to see the people lighting them? 5. How did the mother get her baby not to cry while giving birth? And when did the act of giving birth become so easy in such challenging conditions? (we actually never got to see anything of it, except before and after). 6.Let´s not forget about the magical hearing aid; why is there no explanation about how it works at all?
Secondly: the movie was not engaging, because the characters were undeveloped. The story itself was also thin, and not original. The landscape was like any other post-apocalyptic movie, nor did it make any sense - the family were moving into older buildings (probably because it would make the movie look more dystopian) that in a logical view would make more noise (creaking floorboards etc) than modern ones.
Third: It is really a turn-off when we get to see the monsters in a horror-movie. This movie showed us the big bad monster already in the beginning.
All over, the movie was boring, thin, illogical. The only reason I gave it 2 stars, is because I liked the detail where they used fireworks as a diversion from the giving birth scenario. Although the movie was fairly short, it felt like forever.
