In the film The Book of Eli, the world is in state of disarray, with no government, weak or non-existent town and family structures, and widespread hunger, poverty, and regressed technologies. Is this considered a dystopia?
A dystopia (from Ancient Greek: δυσ-, "bad, ill", and Ancient Greek: τόπος, "place, landscape"; alternatively cacotopia, or anti-utopia) is, in literature, an often futuristic society that has degraded into a repressive and controlled state, often under the guise of being utopian. Dystopian literature has underlying cautionary tones, warning society that if we continue to live how we do, this will be the consequence. A dystopia, thus, is regarded as a sort of negative utopia and is often characterized by an authoritarian or totalitarian form of government. Dystopias usually feature different kinds of repressive social control systems, a lack or total absence of individual freedoms and expressions and constant states of warfare or violence. Dystopias often explore the concept of humans abusing technology and how humans individually and collectively cope with technology that has evolved too quickly such as the car, the flamethrower or the microwave. A dystopian society is also often characterized by widespread poverty and brutal political controls such as a large military-like police.
Dictionary.com includes "overcrowding" as a descriptor, which is definitely not the case in post apocalyptic type worlds where much of humanity has died out.
From these definitions, it is vague as to whether it must be characterized by a powerful government, overcrowding, and advanced technologies, or whether these are just most often the case. Is the world in The Book of Eli, or such worlds as "zombie apocalypses" considered dystopias? If not, what is a better word to describe these "post apocalyptic" worlds?
