A good critic is trying to tell you what she has learned about herself from the reading of a particular piece of literature. A bad reviewer is often trying to tell you how smart he is by declaring whether or not he liked a particular book. If he liked the book, then this is the kind of book a superior person likes, and vice versa. He might try to explain why he didn’t like it, but the review is really just a tautology. “I didn’t like this book because it is bad,” is equivalent to “This book is bad because I didn’t like it.”
