I'm not sure why, but I've always had a love for stories that center around post-apocalyptics. What happens when something horrible happens and the world must rebuild itself. Following are television shows I've been able to find that accomplish this.
I realise that there are many more and I'm in the process of getting them. When I do, I will list them below. I have also left the premise of the show really simple. I don't want to give away much.
