I’m another, though I’ll definitely admit my reason isn’t entirely fair. 
I wanted films of the books, not films based on the books.
I totally get that changed need to be made for the medium, but for me that meant altering certain things and editing/omitting others. Not adding entirely new things.
Gandalf’s cavalry charge down a cliff at Helm’s Deep? Cool for a generic fantasy film, but not in the book.
That’s the point where I decided not to bother with ‘Return of the King’, and certainly not ‘The Hobbit’.
Oddly enough, I love ‘Bladerunner’ but wasn’t overwhelmed by DADOES, and I’m happy with the reinterpretations of Sherlock Holmes stories.
