I enjoyed this more than the very convoluted Dune Messiah, but considerably less than the original Dune. The mysticism and the abundance of statements and dialogue that seem little more than meaningless word salad gets tiring after a while. A key plot point remains rather underdeveloped and some moments seem to clash with what has gone on before in the series. Perhaps some of the tiresomeness also comes from the fact that pretty much every protagonist in the trilogy is an anti-hero, and the few somewhat decent characters are weak and do little else than obey. Nonetheless, it's a fun read with great world-building around a future humanity in which science and technology are mostly rejected in favour of religion, militarism and mysticism.
