I didn't like it. All I really got from this movie is that people are selfish and self serving. The main character is a major jerk. The movie is basically about a car ride with 4 people heading west trying not to catch the sickness.
Along the way they are awful to people. There is really no ending. It's about self preservation-screw everybody else. No hope, nobody in charge of helping to turn things around. Watch at your own risk but I'm sure you can find something better.
