Loved the movie. Tried to read the book and simply couldn't. The author captures the fastidious nature of the house's servants and especially the head butler so well, it made me uncomfortable. Really outstanding structure and word usage, what I got through.
A lot of Ishiguro's works do this; I think The Unconsoled is a fantastic book, but it's so truly painful to read I understand why most people hate it. The Swedish Academy said he "in novels of great emotional force, has uncovered the abyss beneath our illusory sense of connection with the world" which I think is a pretty good description of his style.
Remains of the Day is a great book.
I remember listening to the book on BBC on a program called off the shelf. Such a great book.
