Children of men

Ok, I like to indulge myself in films that delve into the human condition and the occasional chick flick as some call it. Children of men definitely fits into that category but during the film I got so depressed by it that .. I was ready to just shoot myself and get it done .. is this a good thing for a film to incite that kinda of emotion? I think it's good that it's emotional but what a horrible way to start the new year.
