Nice little b-movie concept film elevated by a mostly great cast. Basically M.Night Shyamalan's The Happening done right. Fits right in with some recent cool-concept suspense movies such as A Quiet Place, that focus on family-building elements to encourage more investment in their characters.

Some scenes could have done with a little more commitment to the idea though, and really played on the inability to see. Kind of ruins it in the parts where we can see what the characters can't.

Good to see more A-list actors willing to go to the small screen, and I've always been a fan of Sandra's massive Bullocks.
