Ah, I love you ladies! Selecting characters are one thing, but I just don't think a movie or tv series can get all the details out there that we get in a book. I'm been thinking about this all morning, trying to think of a good treatment of a book turned into a movie. I'm probably going off-topic a little here
but one that comes to mind is Gone with The Wind. Great movie, excellent actors fitting their parts, but yet, the book has so much more. And even though I saw the movie before reading the book, I still say the book is better, and would take that any day of the week if I had to choose. There are always scenes that need to be eliminated, parts that are cut and merged, it's the book that tells the real story.
