First off, apologies for this being so late.
Here is the wiki link for a brief background on all four films :
I have chosen the Terminator series as my Apocolyptic text because it shows the world both before and after the apocolypse throughout it's movies. Although the background story is how humans defeat the machines in the very end (therefore cyborgs are sent back into the past to change the timeline to prevent the future distruction of their empire) I feel it tells a strong tale of the selfishness of humanity, how always striving for the bigger and better will lead to their downfall in a cataclysmic manner. This is seen at the end of the third movie 'Rise of the Machines' showing how Skynet ( the artificial intelligence which leads the machines) destroy's much of humanity in a nuclear holocaust.
On the other hand, it tells the tale of how nature will alway prevail. In this case of an apocolypse, our buildings, cars and computers may all be destroyed, but plants and animals (including the human race) will adapt and evolve to live life in a new world.
