I completly agree!!! The book is the book. The story is the story. Just as we knew it. I'd like the ending is diferent, but it is impossible, reality is as tragic as the fiction is. If the world would be better after preventing the assasanattion Jack-George couldn't go back and would never saw again Sadie in her sixties.
I think the book as we know is one of the most intelligent and wise view of the world history. It makes you think very much.
I also agree with the difficulty of put the book into a film. Its no possible without spoild the masterpiece. Literature is not cinema.
Yes, a tv serie is mor possible than a film. I think all of us thought in the characters and in the actors who can play them. So, the miniseries is the only possibility of playing the story because of its lenght.
