It's awesome to find another fan of Frank Herbert. Which of the Dune novels is your favorite then?Your signature kind of answers that. (I am huge fan of FH.) I like film(/book/comic/etc.) to be consistent, follow certain logic and preferably even clear structure.
There can be a twist and sudden change of subject (From Dusk Till Dawn), but it must fit to the whole big picture.
Also: violence; imaginative, brutal and plenty.
And good use of music is important too.
