It shows a post apocalyptic world where there is little or no sun, permanent rain. Underclass of poor people scavenging on periphery of society. Think about the replicants and their role what has happenend to wild animals/the environment?
How has life become a commodity? What products are being sold by huge advertisements? Why should people need them?
Hope this helps, love the film=).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
