I found the House books (House Atreides, Harkonnen, Corrino) to be average space-opera page turners. The Butlerian Jihad books (Butlerian Jihad, Machine Crusade, Battle of Corrin) were above average space-opera page turners. Kevin J Anderson is unfortunately a "quantity" writer, who never explains in one page what he could take ten to do. This was particularly apparent in his Seven Suns books. Nothing makes me stop reading than an author that wastes the readers time, has badly placed cliffhangers*, and spends tens of pages just to introduce the idea that maybe this group that is obviously not telling us the whole story might just be hiding something. *Hey, something interesting is about to happen and finally move the plot along! Let's pause this characters story and spend the next hundred pages telling an entirely different story!
