Wildly imaginative, deep (def. in terms of detail and description, frequently in other ways, too), intricate works. Expansive worlds to explore.
Cons: Length might be an issue for some. Also, the amazing build-up and tension in some of his books leads to a bit of a let-down at the end (either because you want more, or because the resolution isn't / can't be adequate).
