Updated again on 12-31-17 to change the bottom category from "Nah" to "Not my cuppa tea" based on Deb Nance's "not-my-cuppa" rating on her blog.
Updated 3-24-14 to add one caveat: These numbers from 2008 are all based on how much I personally enjoyed the book. I can't judge for anyone else, so my ratings are completely subjective. As a matter of fact, if I re-read a book, my opinion may very well change, based on what's going on in my life at that point.
10 - Loved it!! Couldn't put it down!!
9 - Excellent!
8 - Very Good
7 - Good
6 - Above Average
5 - Average
Anything lower: Nah
Pean (song of praise) to Nancy, the Bookfool: I was inspired to add "Nah" by Bookfool, who came up with Rating: Nyeh. A light dawned in my brain, as I realized this could be the perfect rating to cover everything below average on my list instead of using all these numbers, as I tried to do before:
4 - Struggled to finish, but not worth it
3 - Annoying - a waste of time
2 - Poor - one I abandoned
1 - Pitiful!
0 - Awful!! Don't bother
