I thoroughly enjoyed my first read-through of Dune. The blend of sci-fi and religion set the stage for a large-scale space opera unlike any I've experienced before, and the power struggle between the large political entities unfolds in countless increasingly surprising ways. I watched the first two (reboot) movies, and there was still plenty here to enjoy!

At times (especially at the outset) it can be a bit slow, but I found Dune rewarding, and the world building a great stage for both this book and the series!
