@retech I was not asking for advice, just curious what other people think.

I read all the Dune books many years ago, most of them multiple times and some I have re-read recently.

When the prequels came out, I started them. The House Atriedes/Harkonnen/Corrino ones were OK, in a nostalgic pulp-fiction kind of way, but the Butlerian Jihad was a truly awful piece of fan-fic. I went as far as starting the Machine War but I just couldn't. I abandoned it and tried to unsee what I had read.
