Having finished the novel yesterday afternoon, I share this critic's enthusiasm. I've definitely recommended it already to several friends. What a heartbreaking, amazingly written story. I'm excited for you to read it. I made my girlfriend watch the movie with me last night and we both enjoyed it (as you say, the subtle nuance was at times captivating - what a performance from all actors involved), though I must say the book was much, much better for its sense of inner monologue throughout. Now that I've read both The Remains of the Day and An Artist of the Floating World, I'm hooked, and I just might go out and buy another of Ishiguro's books today, though I'm not sure which to read next.
I agree, good as the film is, it doesn't approach the intimacy created by the book's extraordinary prose, which for me is on another level.
I've read three other Ishiguro books, The Unconsoled, Never Let Me Go and When We Were Orphans.
The Unconsoled is a rare and unforgettable novel, one of my favourites.
Never Let Me Go is as usual brilliantly written, though I found it somewhat depressing and harrowing at times. And
When We Were Orphans I found somewhat confusing and the least engaging.
For all of these, it's well over a decade since I read them last, but the first two certainly, have left very vivid impressions.
