This one (mostly) holds up well; still an excellent book, with its mix of SF adventure, ecological messages, political maneuvering, and religious themes. Well worth the re-read after many years.

Only suffers slightly from a definite current of homosexuality as shorthand for evil: Piter’s effeminate looks and manners, Baron Harkonnen’s recreational use of young boys, and a few similar moments here and there. Still, while present, these aren’t primary themes, and for me, at least, don’t majorly detract from the rest of the book.
