A book review is a conversation that excludes the author of the book. It addresses the potential reader. A reviewer isn’t paid to be right, just to make a case for or against, and to give pleasure either way…
A critic has some sort of authority, a claim to long experience or deep immersion, a marination in a certain class of literary product.
A reviewer has no necessary knowledge, even of other books by the same author – there’s no shame in flying blind. If a book isn’t rewarding to read in isolation, then there’s no point in invoking any larger perspective…
It’s a mistake to imply that readers are being inducted into a mystery. They’re being guided to pleasure or warned against disappointment.
