The reviews, of course, cannot be separated from the wider context. As Roberts says,
...to cast a cold eye over the landscape of SF and Fantasy as it appeared in 2014 is surely to be struck by how polarised, how ideologically and aesthetically divided it has grown.He goes on to say many interesting things about awards, and the landscape of the genre, and though (of course) I completely disagree with his views on the Hugos, it's a well-presented argument, and I intend to frustrate him by casting a nominating ballot for this book this year. (I suspect he will somehow live with that frustration.)
