I enjoyed the themes of this story more than the story itself. It has a fable/myth feel that kept me at a distance from the characters and meant that the dialogue was often unrealistic in the way old-timey stuff is. I didn’t enjoy that. But the topic of memory, in a whole range of contexts, was thought provoking. War and revenge, marriage woes, grief, regrets - are we better off not remembering those things? I don’t think Ishiguro answers that, he just presents the question.
