Query: if you've seen the movie, you must read this book

Ken Watanabe's character, Katsumoto, the real soul of Tom Cruise's movie "The Last Samurai," is based on Saigo, and the movie's screenwriter has admitted that Saigo's story is what inspired the movie in the first place. This book shows why he was so inspired and why Katsumoto has such depth. Saigo was a complex, brilliant man, a hero in ways that the standard good v. evil model simply cannot account for. And his Japan was a marvelous place where history and the future were in dramatic and dangerous collision. If you love the movie--and, really, it is tough not to love it--you will also love this book.
