The movie is not half as bad as a dozen other similar flicks out there. The premise is similar to the other recently recently movie " A quiet place". Intriguing but yet unconvincing premise at the same time. If u can suspend disbelief for 2 hours , one can enjoy the suspense thrills and compelling storyline this movie has to offer...Great, horror thrill -inducing stuff for those who need you need a dose of apocalyptic horror that works on the senses.. The ambiguity throughout the film keeps it moving and gives a certain aura and charm . Performances especially that of the Sandra Bullock is great and commendable with emotion inducing on screen aura as a mother fights on to save her children...
