Silence on every playground . This is an intelligent sci-fi thriller that doesn't disappoint. It's a bleak and distubing look at the world, two decades from now. Chaos has erupted everywhere as people are overcome by an overwhelming hopelessness. This fear is generated due to the fact that no child has been born for eighteen years. It's a countdown to extinction. Theo(Clive Owen) is asked to deliver a young pregnant girl out of the tumultuous country. To the casual viewer this may not seem like much of a task, unless you can really submerse yourself in the context of the volatile situation. I totally got caught up in the effort, completely absorbed by the significance of this mission. The action really kept me on edge. I was expecting the movie to get too preachy with apocalyptic themes, you know--hell, fire and brimstone. Any religous fanatics would definitely have some valid points. This is touched on periodically, but doesn't go too over the top. I also liked the sarcasm evident when some idiot spray painted a sign that read "Last one to die, please turn out the lights". There's always gotta be a prankster. Overall, I thought this was a great movie--action-packed, original, and insightful
