The Devil Wears Prada gets her just desserts

In light of the Occupy Wall Street movement, I got to thinking about the book The Devil Wears Prada and the movie based on it. As is often the case, the book was much better than the movie.
Maybe this is sour grapes, but I say as both a writer and a reader that the book’s ending was weak. (Spoiler alert) The main character, Andy, finally tells her boss, the monstrous and superficial fashion magazine editor, “Fuck you” and that was pretty much it. The movie’s ending was, alas, even weaker, with the editor getting humanized through a divorce, which did nothing to add interest to her character as a villain IMHO, and in the end being a positive force in Andy’s life.
Here is an ending that I think would have been more satisfying.
I would have had Andy tell off her boss *good and proper,* not just a simple “fuck you.” Since everyone in the industry hates Miranda the editor so much, Andy could have gotten any magazine job she wanted, and Miranda’s enemies would bring down Miranda’s editorship. How the mighty have fallen! Now she has to get a low-paying, entry level job and gets a taste of her own medicine. Or perhaps she could do a 180 and join the Peace Corps.
