It's been a while since I felt that I completely wasted two hours of my life watching a movie. This one did that. Yes, the acting is good, there is nothing wrong with that. But why write or direct or produce a movie that gives absolutely nothing to the audience. It teaches nothing, but presents a totally cynical view of human beings, as if this post-apocalyptic world would turn everyone into these zombie-like creatures unable to communicate with each other, unable to have normal human interactions, unable to smile or have fun. It just shows the writer/director's lack of understanding about life and human beings, and all it reflects is the pessimistic view that he/she currently has about people.
