I wouldn't trash it totally and completely.

While I have very strong objections to some members quoting things that happened in GFR as a legitimate continuation of the story (while I feel that what is presented in the book is no more valid than any ideas that you or I or anyone else might have), there are a couple of interesting subplots in there.

On that basis, on a scale of 1-10, I give it a solid 3.

If you are a true hardcore GF fan, you should read it anyway.
