When films are adapted from books, more often than not, I tend to find the books a lot more enjoyable. So I have skipped watching a lot of films in the hope of reading the books later.
So what are some great films not adapted from books? Or what are some films that are significantly better than the book they were adapted from?
Blade Runner is based on "Do Androids Dream Of Electric Sheep" by Philip K Dick.
There Will Be Blood is based on "Oil" by Sinclair Lewis.
Both were acclaimed in their own right before the film adaptations.
