Tom's Ratings system for book reviews

I tend to be easy about reading novels - if they hold my attention I like them. Because of this, I have one rating for how "good" the book is, and another for how much I liked it. If this sounds confusing, ask yourself if you've ever been highly entertained by a trashy movie (I have). I give books a letter and a number. The letter is the rating for how good a book is, and the number for how much I liked it.

A: This book was a high quality work.
B: This book had some quality work and some trashiness.
C: A really trashy novel.

The very best in entertainment.
This book was entertaing, verging on very entertaining, but there was something about it that didn't sit well with me.
This book was ok. I didn't regret reading it, but I won't read it again.
This book didn't do much for me.
This book really sucked. In some cases I couldn't even force myself to finish this book.

I have to admit that I give a pretty easy "A1". On the other hand, so far I've mostly just been writing reviews for the books I really like -- that really exaggerates the effect.
