As Professor Nobis shows, the five-second book review works.
Ian McEwan's Amsterdam: The first 2/3rds or so of this is quite good. After that, I stopped caring. It got too neat. Up to that point, the echoes, the use of repeating motifs, the way McEwan exploited the fact that one protagonist is a composer to justify and enrich the variations and connections between the various facets of the book, worked. Then, the whole thing just started sounding one note. Again. And again. And even though the conclusion is the fatal flaw of Clive's fictional symphony, I can't bring myself to believe that McEwan intentionally sabotaged the final movement of the novel to echo that failure.
Atonement was better. Saturday was better. The Child in Time was better. But, still, good for a while.
