This book falls outside most genres, and I am surprised it has been turned into a film. Not because it is a bad book, or even because it is non-genre (although that often confuses film makers) but because its strength is the use of language and description of people, moods and food. This is wonderful on the written page but never easily tranfers to film.
The beauty of the book is its timeless appraoch to people, religion, feelings, and the textures of life that are often not written about. The book covers a lot of ground, dealing with different types of people (each with their own voice) with their loves and interests and fears and jealousies. It has a bit of memories, but mainly it is based in the small village, and the richness of texture comes from the characters who populate it.
It is a book that could appeal to all, certainly anyone who has an interest in what people are like, and how small communities only need a minor event to change their outlook and (small) world-view
