You have a good point there, I don't like Clancy, Childs or others like that because the dialogue crowds out the narrative. Screenplays masquerading as novels.
I like storytellers and am not ashamed to admit that my favourites are Bernard Cornwell and GMF.
The problem I have with Cornwell is that he only has one story: all he does is translocate the dramatis personae in each series, but tells essentially the same (episodic) tale of a flawed hero manipulated by a scheming superior.
At least Herbert's arc doesn't repeat itself.
