Entertaining at times

Rating: 5/10 (8 April 2018)

I've just watched the film. It is interesting at times and have some good scenes but I found it repetitive and shallow. There is not much character development and Emily Mortimer's role is excessively passive. It looks like they have the (good) idea and tried to expand it until reaching 90 minutes.
I don't want to spoil anything but where do they get the power from? And all the hardware? Not vey believable.
Also I've studied sign language and have met plenty of deaf people. In my experience, most deaf people are quite noisy, precisely because they cannot hear the noise they make. The protagonist of the film wouldn't go too far. (Neither the audience, slurping and making noise with popcorn and other crap food).
