Do you judge a film based on how faithful it is to the book it is adapted from? I am one who will judge the film for on it's own ground. For example, if a film is solid, but completely bastardizes the book that is was adapted from, I will disregard the book, and solely judge the film. That's how I feel it should be. Sometimes, changes are necessary. Sometimes, changes aren't necessary. I try to eliminate bias from equation when judging these kinds of films, and judge the film on it's own merit. Take Harry Potter & The Prisoner of Azkaban, for example. The film changes alot of things from the book, but it was still a wonderfully made film, despite the changes (necessary or not). Alfonso Cuarón made a great film, and it is my favorite Harry Potter film.
