I know its nerdy but I absolutely hate when movies of classic books think the story needs to be changed (I'm looking at you, Peter Jackson).
In a vacuum I don't love the changes he made to Part 2 but I can also see how they will make it flow much better into Part 3 than Dune > Dune Messiah ever did (that always felt disjointed to me); as well as make that story more compelling.

"Alan Smithee (also Allen Smithee) is an official pseudonym used by film directors who wish to disown a project."
Not really. The biggest issue is time. As far as i noticed, one needs 2 hours of movie for 100 pages of a book. Anything below this (fitting 400 pages in 2 hours) is art. That's why Lynch's version is better.
Here’s more into for anyone interested.
