This question can go for books/movies, comics or really any adaptation. What does a director adapting a piece of media have to prioritize? If this director sees the ending of a work and decides to change the ending to fit his own view, has the adaptation suffered because of it? Imagine a scenario where the ending is, on an objective level, neither better, nor worse than the original ending. Is the new ending a poor adaptation on the sole basis of its deviation from the source material? Or conversely, can the original intent of the author be bent to serve a new story?
something that's definitely been on my mind some with specific examples: Soul Eater, Tokyo Ghoul, and the upcoming speculation whether Attack on Titan will have an anime-only ending. – lavenderhatchet2 years ago
I suggest the analysis of the example of the (in)famous ending of Usagi Drop, which was changed in the anime and live-action adaptation and was very welcome because the ending in the manga was just unnecessary and horrifying. – Beatrix Kondo2 years ago
