A two hour build up with an very poor ending

Rating: 2/10 (24 December 2018)

Ok, so I'm not gonna jump in the "it's a ripoff from "A quiet place", even though the setup is VERY similar and, even if this is based on a much older book, the timing to release a movie like this doesn't feel like a coincidence. Anyway....
I think the most unsatisfying things of this movie are:
A) We never get to see the "creatures", I know it's part of the mystery and stuff, but at least we could have a quick glance by the end of the movie of something....al we see is leaves rising from the ground (and some drawing from one of the characters who actually saw them)
B) Most of the characters are cliche and don't really matter except from the protagonist couple. We are presented with like 10 people from who the whole importance is that one of them is also pregnant (boy, I wonder who are the two children with Sandra Bullock back to "5 years later" when the film starts
C) The ending. So they reach this blind people school, ok cool, blind people are immune to the creatures, so they are gonna stick there forever? is that the happy ending? will they have enough supplies for all the people forever in this house in the middle of nowhere? This feels like a really loose end, kinda like the author didn't know how to conclude the story
If you have to choose, watch "A quiet place", similar premise, but much better achieved, better monster (yes, we get to see them) and the acting overall is much better
