Movie or Book

When if ever can a book and a movie coincide enough to keep the integrity and the author's vision? Scences missing and added all willy-nilly, bad acting and cheesy love scenes make for a bad B-rated movie. Which do you prefer, the written word or the screen play? That is the million dollar question of the week. Can anyone answer that or do you even care?

Wading through the language of days gone by takes a patience I have yet to master to any degree. At just chapter three I've learned that I need an interpreter for many of the colloquial phrases used. If anyone can give me rundown on what is really meant in the letters at the beginning of the story I would appreciate it.
