I just watched the movie-adaption and in about 2/3 of the scenes I was like 'Whut? I don't remember that'
(this is one of those scenes...I am quite sure that I would have remembered that)
Now I have the suspicion that the adaption was simply not very close to the book (still fun, though...I know that sentence will get me kicked out of the book-geek-club) but I also noticed that I forgot most of the book.
So: re-read!
I can start even more books and never finish them!
