While there was repetitiveness, I didn't see the one-dimensionality that the other reviewers have seen. I think the problems with several of the characters were fairly in-depth. Also, not all of the antagonists are set up as truly evil. The world is intriguing, as is the magic system, and the repetitiveness goes away after the first couple of books. My husband and I both read the entire series, and the sister trilogy, all the way through.

It's not a heavy read, but it is a fun one. :).
