Anyone who doesn't like this book either has expectations of what fantasy or action/adventure books should look like or just doesn't get it.
If you expect a 3rd book in a 5 book series to be a full story rather than a part of a story you might be disappointed.
I was not disappointed. I found it better than the second book in a lot of ways. There was a lot more dialog and interaction with the dragons and ties the second book in nicely. I can't wait for the next book!
