I know, right? You read a book you love, you look forward to the movie, and then half the book - always the better half - is just missing. I mean, the reason is clear - you can't actually get everything INTO a two hour movie - but it's frustrating as hell. On the other hand, how many books did you actually love so much you really wanted to SEE every little detail in the movie? You have to have an almost religious attitude to a book to love it that much.
