I hadn't read the book in a while when I saw the film, so it was still pretty fresh to me, which is the best way to watch it. You are able to see the film and the book as two seperate entities that way. I thought it was a good film, it could've been tightened up here and there but thoroughly enjoyable and I bought the DVD after seeing it the cinema so it's safe to say I enjoyed it.
Bit annoyed that A&D won't be out until winter next year, it's a heck of a long wait but I reckon it has the makings of a better movie than DVC did. The plot seems much more movie like than DVC.
