My Dune journey was a bit different. Played Westwood studio's Dune 2, then Virgin's Dune. Loved both so much I watched the movie, which I enjoyed. The recent miniseries is ok too.
Got enthused about reading the book, found it esoteric, especially with all the terms Frank throws in. So put it down for a long time.
Then got into Brian Herberts and Keven J Anderson's prequel, I couldn't put the book down, read through all those.
Then gave Frank another chance, on the second try found it wasn't bad.
