Anyway, I visited to The Complete Review and it appears that the two reviews I read were, in fact, the most negative. As with other recent Roth efforts it seems this book is generating a wide spectrum of responses from the critics.
Here is a sampling from the Independent:
So the story rushes heedlessly and humourlessly on. Like a miner who puts up no pit props, there is always a danger of the story collapsing behind him, and it does. (...) The book is a tragedy, but not in the way Roth intended.Ouch!
