I just don't expect the movie to be like the book anymore and then am not let down. I go in expecting a different twist on the story as it usually is and then tend to enjoy it. I used to be so disappointed when they weren't the same but they can never match our imaginations of the written print or someone's interpretation from the print. I actually now appreciate it that it is not the same exact thing that I read; it is something different, not so predictable. Occasionally it is kept true to the story and is done well, such as in the case of the Potter series; I can appreciate this as well and very much enjoyed it. This is so rare and difficult to do as everyone has their own ideas and imagination when they read something. Too many people involved in the creative process of making a movie.

Expecting something different, you might be pleasantly surprised by someone else's take on it and opened up to slightly different characters and story, not the same thing instead of being disappointed that they aren't the same. Chances are they won't be.
