Reasons for the difference between film and graphic novel
I actually read the graphic novels before I saw the film. I knew there were going to be differences, there always is. So I went in to see the movie not wanting to compare it to the graphic novel.
I found I quite like both, for different reasons and in different ways, so I've no desire to 'bash' either of them. But I am endlessly curious as to why they decided to make such drastic changes to how characters were in the graphic novel. Did they give a reason for it? Or was it simply decided by the screen writers that they liked the setting but wanted to do their own thing with it from the start?
