I apologize for being first to comment.
Co-incidentally I was recently recommended this book by a librarian friend and had just dipped in and then out and returned it when your article appears.
I found it flat and unfunny. There wasn’t a single story that grabbed my attention enough to finish, though I finished a few. It’s possible that I am not the correct audience/age (though the librarian and I are similar in age and enjoy some of the same books/authors), I have the belief that comedy and writing are not age/audience bound or shouldn’t be.
