Slow start, into a great horror/suspense

Rating: 8/10 (10 April 2018)

This movie is a slow burn for the majority of it. If you can't sit still and get bored easily, you might have issues with the first 30-40 minutes.
There is very little dialogue, most of their communication is with sign language that is subtitled. No big deal for me, but some people will hate that.
Having said that, once the movie gets going, it is quite entertaining and very suspenseful. There are 2 or 3 well placed jump scares, but it doesn't rely on that for the only strong reaction from the audience.
There is VERY tiny amounts of exposition in this movie. You only get glimpses of old newspapers to see why and how they are in this predicament. I felt like I could have used a tad more with the ear pieces, I didn't really know what the plan was or purpose was for those, but I get the general idea. I have no clue how they work, and would have liked to have some more explanation on that. Otherwise, you really don't need any exposition and it is all right in front of you.
You get a real sense of dread and what a miserable existence these people have due to the situation they are in. Everything they do must be as quiet as possible. Just dropping something on the floor could mean the death of the ENTIRE family. Thinking of having a baby in this situation is horrifying.
Horror movies seem to have WAY more misses than hits these days. I thought this was a fresh idea, the antagonists were well thought-out and original. The effects are good, and they did awesome with an idea that could have fallen on its face due to the pace and complete lack of dialogue. People are impatient these days, many want everything explained and don't like subtitles. They want the story to be in your face from the start. But. this movie really pays you back for the smoldering beginning.
I give this an 8/10. If you are a patient person who likes a slow burn that ends in a bang, you might really enjoy this as well. I would compare the pace and payoff to 10 Cloverfield Lane in a way...
I would suspect that the vast majority of negative reviews are from people with short attention spans.
