The Lord of the Rings did an amazing job adapting the books and opening them up for a wider audience. I'm a Tolkien nut who's read everything by the man that I can, my friend's never even read
The Hobbit and we both adore the movies.
I'm going to say that
Atonement is a wonderful movie. But I've never read the book...
I am really hoping and praying that the new
Watchmen movie is faithful to the graphic novel. If it's faithful, it'll at least be *decent* by default.
