Anime is an especially unique form of storytelling. In other mediums, deviations from the source material are acceptable and can make the adaptation stand out. When creators make changes to adaptations, they often do it with the thought that the adaptation should be unique in some ways since it's already been seen before. Among anime fans, however, unfaithful adaptations are often frowned upon.

Audiences prefer "complete" adaptations that bring scenes to life in animation. Unfortunately, some anime adaptations are cut short or have to make major changes. Cutting manga-only characters from anime adaptations is a common occurrence when changes have to be made.
