Literary adaptation is a tricky thing. Some of the best movies are actually straightforward adaptations of books (Rosemary's Baby comes to mind), but some of them deviate so far from the source that it may be difficult to know which work inspired it. However, I love it when a director can sometimes create truly magnificent work that won't use a word of the original text but can still channel the spirit of the original work properly.
*Suggestions are welcome. The main thing is that the work itself cannot be a straightforward adaptation (like the Harry Potter movies). Examples are below.
