Should it have been published?

I wish they had obeyed GGM's wishes and not published this unfinished work. It is a collection of 5 stories about a woman who visits her mother's grave on an Island every August and finds a lover for the night. If hadn't known that the author was GGM it might have been more enjoyable as his writing is still fun, colourful and thought provoking. But I felt as disappointed as I do watching Mick Jagger on stage at 80. Such a thin performance compared to his earlier works.
