Dumb show

Rating: 3/10 (20 August 2018)

The narrative premise of this film is brilliant---the characters are forced to remain silent, so the audience has to work out most of the background and exposition for themselves. And there are some nice touches, such as the resolutely unlooted vending machine full of potato chips in the supermarket.
So you're brain is constantly engaged in working out what's going on--for example, that the reason the family are all so fluent in signing is because the daughter is profoundly deaf. But this high level of mental engagement means that you are also constantly spotting the multiple inanities in the plot.
Suspension of disbelief is all very well, but this film mounts such a reletless assault on common sense and logic that it is impossible.
Perhaps best seen a cinema where you too have to remain silent and can't voice or hear an objection every few seconds.
