The Art of Fiction gives writers (and readers) tools for thinking about how writing is done, and specially how Ms. Rand wrote. If you read her books, you will particularly find her insights to her own works very helpful. She is speaking of "romantic" literature as opposed to "naturalistic" literature, and shows the differences in the purposes of these types of literature. Much of the criticisms leveled at a book such as "Atlas Shrugged" can be understood in light of the specific type of literature that Ms. Rand wrote, and the purposes of such a type.
I read the reviews before I purchased the book, and find the criticism to be a bit strange. Yes, Arn Rand thinks she is a good writer, and shows examples of other writings that she deemed require improvement - one would expect as much given the purpose of the personal talks that she gave to a group of friends and interested acquaintances that were later edited into this book. The book is short and rather episodic, rather than flowing - again a product of the converting informal lectures into a book.
In any case, as someone who wanted to use the book to become a better reader, I found it very insightful as a reader in general, and specifically as a reader of Ms. Rand.
