Pretty good, though not always the way I read them. She calls Carrot a side character. To me, one of the most amazing things about Discworld is that what would be side characters in other series are, over the course of the series, as fully fleshed-out as most authors' main characters. We know as much of the important stuff about Carrot and Angua as about Vimes and Lady Sybil.
The first comment was another excellent intro to the books, in a lot fewer words.
