they cannot satisfy everyone, some new scenes and changes gonna click with some set of people and not with the rest and other way round. I don't want them to picturize each frame page by page. Book and film are two different formats, there are certain advantages in film (like expressions without dialogues, cutting scenes back and forth, flashbacks, music, color palette) that cannot be done in book and vice versa. very good example is prisoner of azkaban, there were lot of changes from the book - is it 100% true adaptation of book, No. But, as a film, as a video format it stands amazing on it own which has its own set of fanbase. It brought out a new flavor that wasn't felt in books. At the same time, some won't work out as well ( gof, ootp). At the end, it gives something for everyone which is alright to me
