By Having the Stephen King seal of approval bestowed on your film is a sign you've made something truly disturbed and unhinged.
Not that it's an easy accolade to get. The prolific novelist who wrote Carrie, It and Cujo famously doesn't even like the beloved film adaptation of his own book, The Shining.
New nearly-silent film A Quiet Place, however, has earned the respect of the influential author, with him calling it, "an extraordinary piece of work".
In a tweet, King praised the effect the silence has on the visual impact of the film, "in a way few movies manage."
In the film, Blunt and her real-life husband John Krasinski play a couple trying to survive in an apocalyptic US one year after it is attacked by blind monsters with a particularly good sense of hearing.
The couple have two children, one of whom is deaf herself, and together they must live a soundless existence in order to survive. When the couple find out they are expecting another child they must work out how to keep the newborn silent before its imminent arrival.
The film, which is also directed by Krasinski, has been widely praised. In The New York Times, Jeannette Catsoulis wrote that it is a, "convincing portrayal of a situation where a rusty nail is as lethal as an unexploded bomb, and the few remaining inhabitants seem — much like the audience — more likely to die of stress than anything else," adding that, "the movie rocks".
It also managed the rare prize of earning a 100% score on Rotten Tomatoes for several days, only recently dropping to 97%. It comes after years of heightened interest in the horror and thriller genres, with Get Out and It making 2017 the biggest year for horror films on record.
'A Quiet Place' is in cinemas now.
