Query: How can a great story disappoint so...

I came to write a detailed, critical review of Chainfire only to find so many others expressing my exact sentiments. Great storyline, great characters, but too much rehash, too much philosophy, too much (I hate to say it) "fill" for too little advancement of the story. One other reader beat me to the punch: "Unfortunately, other than rehashing what I've ALREADY read in his other books, not much happened. I especially felt cheated in the end, which I won't ruin, but it felt like half a book."As other reviewers have commented, I will continue to read the series to conclusion (if it ever has one); but I am disappointed in the author for being so unwilling to move along. I find myself skipping more and more rehashed prose until I find something actually happening. I must admit that I have started getting the latest release of this series from the library rather than purchasing it. And I love building my library of books that I own!
