This movie will make you wish you'd never been born. Each minute that you continue to watch this movie you will find your will to live quickly being sucked out of you. If you haven't killed yourself by the time everyone busts out dancing in the McDonalds, that will surely send you into a hatred for life for which you may never recover. Unfortunately I don't own a gun or I would have taken my own life and saved myself from having to watch the second half. The scene where they drive Mac into the desert and he holds up his hands and does this stupid whistle to find his family which are almost dead in a cave made me start bashing my head against the wall in hopes that I would black out. Sadly I did not, and I now I must live the rest of my life with the nightmarish memories of this movie. I feel depressed and hopeless. I pray everyday that aliens really do exist and that they kill every last person on this planet. We don't deserve to survive as a species if we can make a movie like this.
