A Neat idea for dumb audiences.

Rating: 6/10 (9 August 2018)

No need to go into plot.
When the whole plot relies on a gimmick, the plot needs to be good. The gimmick is "sound triggers death". The plot is "family tries not to make sound to avoid death."
Similar to the movie LIGHTS OUT, the gimmick is intriguing until you realize the filmmakers assume you're stupid because the characters make stupid decisions.
Maybe not try to get pregnant a year into an alien sound epidemic?
Emily Blunt is a goddess of talent, & director Krasinski found a good crew that made him seem skilled, but any horror movie that shows it's antagonist in the prologue does not know what horror looks like...
Imagination is scarier than ANYTHING you can show.
