I’m a big time Ishiguro fan and can’t for the life of me understand why his books are rated so low on Goodreads?

My hunch is that he doesn’t always go for the happy endings, not always a perfect resolution, and can leave someone unsettled but the books themselves are great works of literary art. It won’t end like some superhero movie with the good guys saving the world from the bad guys

But am I missing something?

Also no spoilers on any of his books!
