"But the entire point of the slippers is to make Nessarose walk." In the Broadway show. Let me repeat that. In the Broadway show. The Broadway show was based on a book. A darker, more mature book that I've never read, but a book nonetheless. And guess what? Nessa could walk in the book. The slippers were still there. It's not the end of the world if they change the slipper aspect in some way in the movie. The movie isn't the Broadway. It's inspired by the Broadway show. That's it. Get over it.
