Most of my friends laugh at my collection, because I have a thing for post-apocalyptic movies. Funny thing is, most of our culture (especially the younger folk) do as well. In a secular culture that has no narrative of a beginning... a narrative regarding the end has to be made up. Consider it the joy of living in a postmodern matrix. Our reaction of some random scientific situation beginning our world means that some other random moment will end this world.
These movies provide a secular prophetic narrative, hopefully showing the woes of societal disintegration and causing the viewer to beware of what led to it. Whether it is the war machine, a random zombie virus, or the aftermath of a culture barely functioning and feeding off itself, these three movies provide just a hint of the story that folks and trying to write. By pointing out what could happen....the hope is that we now will change to avoid it.
The genre is one of my favorite (trust me...Zombieland is very entertaining) because it is sometimes humorous, but more in how it tells the story a world without the Triune God is hoping to avoid. It is our culture trying to imagine how a world that was never created can implode.
This is why I think about these things so much. As a church, we should be telling our story...from creation to end.
Glory be to the Father, Son and Holy Spirit;
As it was in the beginning, is now and ever shall be
