I think Le Guin's novels are smart. The Dispossed & Left Hand of Darkness are exploring themes of politics and sex relations more than most sci-fi dares to dwell. The Lathe of Heaven was a good look at management gone awry and how power in the wrong hands can harm when it is pretending its doing good but with it's own agenda. I read an interview with Le Guin in which she said she would never write another book like The Dispossed because the years of research she put in to it was for the young and she no longer is. Darn - I was going to go on and on but The Spanish Prisoner is on and Ive been meaning to catch that film.
