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. I didn’t enjoy Margaret Atwood’s The Blind Assassin, which I thought structurally defective and basically novelettish. Its winning the Booker in 2000 didn’t prove me wrong, any more than it would have proved me right if I had liked it.
