So, here is my ratings system:
It was awesome/unbelievable/fantastic/amazing (pick your adjective)! Basically, I loved it. Buy it, put it on your shelf and read it again and again!
I liked it! I'll probably buy it if I find it on sale. It was a good book. I might read it again.
It was ok. I won't buy it and I won't read it again. It was good enough to read once.
I didn't like it. I read the whole book, but it felt like work and I got no enjoyment from it. I will be deleting/donating my copy of the book.
I hated it. Or I didn't finish it. I will never allow the book to darken my doorstep again.
Ok, there it is. I will start using this on my next book review. I will also put a tab on the blog with the rating system available for all to peruse. Hopefully, this won't make me seem like a big meanie, but it was time to add it.
