An American horror thriller; A story about a mysterious force which when encountered ravages people to suicide. This is a post-apocalyptic film and bears some resemblance to "A Quiet Place" (2018) in terms of a threat based on natural phenomena. Unfortunately, despite its strong production values and good tension, this story evetually allows melodrama to seep in and it loses direction. Clearly, a memorable movie but it lacks emotion despite Bullock's intense performance.
