Interesting that the editor of the trailer chose to follow the Lynch trailer.
Supposedly, no publisher liked the book, and it couldn't get published except by a publisher of car manuals. It later won a Hugo and Nebula. And then it was beloved. As a child I struggled to get into the novel but succeeded on the second or third try, loved the wonder and political intrigue. Perhaps I was too young.
Supposedly, no one liked the first film, claimed to be confusing, and Lynch disowned it. I understood it and loved it.
The second was supposed to rehabilitate the book's image the Lynch mauled. At first critics claimed it did, and later it was also proclaimed a disappointment. And then critics came out saying that they actually liked the Lynch film better.
I found the debates strange as I liked all three: book, movie, miniseries. Movies are an odd translation, especially with anything so complex as Dune.
What is confusing is how people can judge a movie based on a trailer. Some trailers suggest a bad movie if you can't figure out the general plot.
However, it's difficult to get the general idea of the plot out of these trailers--probably due to the complex plot--although they do touch on some of the wonder.
