For those interested, Le Guin has posted Gedo Senki, a First Response on her website. It's a good read. I have to say it is such a treat to read her reaction to the film after having seen it. The movie is quite different from the books in many ways. What she told Goro Miyazaki, the director, was "It is not my book. It is your movie. It is a good movie." And I really think that sums it up. Her response does contain spoilers.
