I suppose foul language and general coarseness of expression does qualify as "conversational style" these days. I found the Elle excerpt difficult to get through and it's not long. I will withhold judgment until I get hold of the book and come to it with an open mind, but I sure hope the whole thing doesn't read like that.
This put me off also. I'm not saying they should gush about how much they love it, or not be frank about the challenges involved, but at least show some respect and/or take a minute to explain its quality to the reader. At least NYCB's seasonal cash cow is a masterpiece, not something many other companies can say.
Thank you, ECat, for starting the topic! I look forward to hearing people's views, and I imagine they'll be lively reading.
