I disagree with the negative reviews

Rating: 8/10 (3 January 2019)

The reason we are left unanswered questions is because the director wants us to be blind just like the characters in this movie. We don't see the creatures because the characters don't which further entwines us into the story and makes us feel like we are really in it. The whole point of the movie would be pointless if you saw the monsters. I think people need to do research before they post a brain dead review not knowing what they are even talking about.
Yes it took inspiration from a quiet place but the whole point of film is to influence others and create content that will be appreciated which for me it certainly is. People need to stop expecting to be spoon fed everything and just deal with a bit of mystery. If you don't like this movie then I'm sorry but you have no idea about film, get back to watching the happening for Christ sake.
