I knew I had to have patience with Dune, but I wasn't expecting at times to still be struggling to understand exactly what was going on in the last quarter of the book. I don't want to penalise the book too much though as I did struggle to find long periods of uniterrupted time to read whilst I was awake and alert, so that probably had an impact on my enjoyment and comprehension.

The appendices at the end of the book were great providers of extra context — though I really struggled to fully grok the one on religion — and watching the 2021 Dune: Part I film, which was excellent, really helped to increase my appreciation for this story.
