Many people bash populer film because "It didn't measure up in the exact way they thought it would.
STOP PEOPLE!!! Stop your too Critical Analysis sometimes.Stop your phony rebukes.Just STOP!!!
And accept film the way they come.
As a one time penulis of a book called Elfin Magic (become a fan of it:link)
I think i can speak for all(or at least most)authors when I say It's FINE!!! If someone offers anda a direct line to the film and the penulis refuses because the director says some plans that differentiate from the book and someone refuses then they are just stupid!!!
