Interest thriller

Rating: 7/10 (13 August 2018)

I'm sure all members of a family have wished for peace and quiet at some stage but here we have a group who can only communicate by sign language.
Some monsters from somewhere that can't see have invaded our Earth and killed most living things. I'm not sure how they would have been able to have built a civilisation advanced enough to manager interstellar distances if they couldn't see but never mind. Even if they came from within our solar system it would be quite some achievement.
So exciting in parts and well acted but these monsters - or indestructible Angels of death according to one newspaper clipping - had a fatal weakness - high frequency sound.
Why this wasn't picked up by World scientists is unknown - also one of them was despatched with a simple shot gun yet they'd somehow managed to survive much more powerful weapons when the World armies must have fought them.
Still it was enjoyable but deeper thought was needed to make it more plausible.
