The movie tries to deal with how people in a crisis lose sight of their humanity and would rather mistrust each other or leave each other behind than work together towards a common goal. It’s a bit sad when you think that’s where humanity is right now. It also tries to deal with our dependence on technology and the fact that many would not know what to do without their smart phones or smart tv’s. I won’t spoil the movie if you still want to watch it but with such big name actors they could’ve done a better job and at least a better ending. It builds you up and then lets you down. I love Julia Roberts but this film was not worth it.
