One of the problems with the Lynch movie was , in my opinion, trying to tell too much
of the story...trying to get in all that's in the first book.
This lead to many of the characters being a mouthpiece of exposition, including their inner dialogs.
The miniseries had more time to slowly get the story out.
I think a new movie would perhaps have to be streamlined and focus on creating an entertaining film that would inevitably be less complex than the book.
I even agree that a new movie should merge Gurney Halleck and Duncan Idaho as a previous poster said he'd heard.
