Not the same guy, but I started reading it a few weeks ago and just finished the fourth book last night. It does a pretty good job at both world building and character development in my opinion (though it really shines across books). In my opinion, the first book does a good job of introducing new elements of the setting at a good pace, and uses it’s characters who know little of the world to impart how special/rare some of the things are.
Oh, yeah, they have a reputation for being long. There are 14 books total I believe, and each is pretty long.

That said, I was able to read the first the books with an average speed of a book a week (though I spent a lot of the weekends to do so), so I wouldn’t say they’re crazy huge books.
