We need movies like this which awaken us to how thin the line is between everyday normality and the brutal reality of the world. How horrors can appear out of nowhere and without any obvious cause and destroy our complacent petty existence with the same amount of compassion as an owl swooping down on a prairie dog. It's a movie that's a question mark that becomes many question marks and ends with the only answer possible: hide. If you watch this movie you should realize you're watching something that is far from implausible and you could be the lead actor in the show tomorrow. I see a lot of lousy misguided reviews for this movie, don't believe them. It's damn good.
