"The purpose of a review is to describe the book. There is a tradition of reviews
being evaluative, but I don’t feel that this is their true purpose. My basic
complaint about reviews in general is that they are too concerned with
evaluating books rather than describing them."
"I can’t stand reading reviews that offer only, or mostly, the reviewer’s
opinion. Why should I care about a reviewer’s opinion? I’m reading to learn
about a book. Tell me about the book. I don’t care about you. I care about the
book. Just like you don’t care about me, you care about the book I’m reviewing."
