It is a well known fact that the World War Z book so far from the movie that Brad Pitt should just basically be cancelled (this is a joke). The book is an oral history of the Zombie War,tracing events from the initial outbreak in China until years later when the Zs have been all but defeated. It features interviews from people from all over the world speaking of their experiences and stitched together to form a coherent record of the events. There are many stories told. Some are plot drive, meant to explain how things happened and the timeline. Some stories are there for the texture, to show hoe different people in different parts of the world survived, or didn't.
I loved the documentary feel of the book, since it is made up of "interviews". I love the writing, I love the stories. Some scary, some heartbreaking, some hopeful, some celebratory, and some, even prescient. I don't know how to say again and again that I really really really love the concept of the book (it hits all my post apocalyptic and documentary spots), then he nails the execution. I really think this should have been made as a TV series. Even like a "mockumentary", but serious and with reenactments. One can only hope, that like the Zs, this story will rise again, to be told in a visual medium, much better that the last time.
