I think that most people believe that a product with no flaws deserves a 5, and they then deduct stars based on perceived flaws. This is what leads to a lot of 4 or 5 star products. Under this system, a toaster, say, with a 3/5 rating is not something you would buy because it had too many flaws.
However, under the "average" rating system, a 3/5 toaster would be what most people would want, since it would be a perfectly fine toaster. And there may be no 4 or 5 star rated toasters at all.
Kind of how a "C" grade, originally being average, is pretty much a bad grade now, with "D" and "F" being, basically, failing grades.
I agree that only people who buy the book on Amazon should be allowed to review it. If you haven't read it, how are you entitled to an opinion?
For ratings, mine work like this:
1. Horrible - Usually quit after the first chapter
2. Very bad - Often dropped half way through but occasionnaly plod through to the end to see what happened.
3. Good - Decent book that I enjoyed. Worth reading once. May read again.
4. Excellent - Loved the book, enjoyed the characters. Will read it again and it needs to be in my permanent library.
5. Brilliant - Totally engaged me. Possibly changed my life. I have to find more in the series. Must own it - am evangelical in my praise of it to others. Only about 5 out of over my 200 books in Calbre are rated at this level.
