A novel in which everything is perfect is waxwork

I find this in the NYTBR Jeanette Winterson review of By Nightfall, the new Michael Cunningham novel. 

I find it, and I celebrate it:

Good novels are novels that provoke us to argue with the writer, not just novels that make us feel magically, mysteriously at home.  A novel in which everything is perfect is a waxwork.  A novel that is alive is never perfect.
