Well, I've never read the 6th and 7th, precisely because I lost interest after reading the 5th, which I found confusing and unengaging. That said, I was relatively older when I read the fifth book, so my tastes may have changed in between.

If you liked the earlier books, I'd give it another try. I also thought the 5th book was the worst, but 6 and 7 are my favorites of the whole series.
