What is a really good book to movie adaption that you've seen?

I feel that The Road is a really good example of these kinds of movies.
 
What do you guys think?

The Shining.
The ending is very different, but the movie is excelent notherthanless.

The black and white To Kill A Mockingbird. 

Fellowship and Two Towers.  Jurassic Park.  The Godfather.

Ghost World. Best comic book movie ever. Yes, better than Spiderman. One of my favourite movies of all time.

The Godfather

The Neverending Story, Fight Club*, Jurassic Park, The Remains of the Day, The Fellowship of the Ring + The Two Towers, The Silence of the Lambs*, A Clockwork Orange*, 2001, The Green Mile, Das Boot*. American Psycho.
 
 
* better than the book

 "Children of Men"
All the Lord of the Ring's movies
"Shindler's List"
"Harry Potter and the Prisoner of Azkaban"
"Harry Potter and the Goblet of Fire"
" Harry Potter and the Half-Blood Prince"

LoTR of course.

FIght Club >>>> All.

Lord of the rings is the easy answer. 
 
I am legend is pretty good too. I guess when you fuck up the first two movie adaptations, you're bound to get the third one right. Third time is a charm as they say.

As far as I can recall "The Exorcist" made a pretty seamless translation from book to movie.

Some children's books make the transition very well.  Mary Poppins, The Black Stallion, The Incredible Journey and Never Cry Wolf are excellent books and movies in my opinion.
