This book does not present, directly, the plot synopsis of the film.  This is a book about the art of, and the making of, Rango; not about the story of Rango -- although one can be worked out by following the progression of the introductions of the characters and the scenes.  For the reader who wants to know how a modern CGI animated feature is made, without dwelling overmuch on the minute details of how the animation process works, The Ballad of Rango hits just the right mood of you-are-there, over-the-shoulder glimpses of Verbinski and his key production people as they labor, and of the multitudinous cast in drawings and in close-ups of the three-dimensional models as they “act”.

Even if you saw the movie several times, you will learn something new about it here.  You will spend longer poring over this book than the running time of the film.
