Short answer: there are none. At least, not in my opinion.
Long answer: Books allow for an extensive amount of detail to be given to the reader, allowing the reader to build a very clear image in their mind and build their own world out of the pages in the book. A totally unique world that you become attached to, that you get invested in. A movie is one person's interpretation of this book, and it is very subjective as to whether or not it is good. But the majority of the time, it wont match your own interpretation and therefore wont live up to your own self-made expectations and wont represent the world you've built yourself in this book. It would be incredibly hard for a movie to surpass your own imagination, especially if you really enjoyed the book.
The only time I can see a movie being better than a book is when the book doesn't give much room for detail, or you don't enjoy the book. But then, those are rare circumstances, as if you didn't enjoy the book, why see the film? And if a book doesn't give room for detail, it's hard for a movie to really give a good representation on-screen.
