Anytime a significant change is made to a character in an adaptation, especially one as well-loved as Dune, it’s certain to catch the attention of pre-existing fans. However, when writing for a modern audience, the inclusion of diversity is an important point to focus on. In order to make sure that Dune's story, which was written in the 60s, still felt relevant to a broad audience today, a few changes to incorporate some diversity were essential. Considering there aren’t many powerful female characters in the Dune novel (aside from the Bene Gesserit), some were going to have to be incorporated into the adaptation to create more of a balance.
