This is interesting! I read the book first and I felt that the movie was so much more obscure as to the chatacter's motivations... It felt to me like the movie was trying to be several things at once, and though it might have been good in movie terms, for me as an adaptation of the book I had loved it fell short.

But then I often thing that from the mbook or the movie, whichever one gets to know first keeps a sort of forever upper hand, so maybe it's just that.
