The main defense I see for Villeneuve's changes to Chani is that "she wasn't much of a character in the books." But plenty of characters have even smaller roles than Chani. Does that mean they all need to be rewritten to have bigger arcs? Not every character has to be the focus. For the first three books, Dune is fundamentally Paul's story.
I'm also perfectly happy to be on the side of those who love the books as they are. I've seen people dismiss that perspective by calling us "annoying book purists," but that's just a way of waving away a legitimate interpretation. If someone thinks Chani is underwritten, that's a perfectly fair opinion. That doesn't mean that everyone else has to agree. Too often, the defense of adaptation changes boils down to, "That part of the story always sucked anyway." However some of us genuinely see more nuance in Chani as Herbert wrote her. Some people see weakness where others see strength.
There's also a common assumption that Chani's loyalty to Paul is a flaw because Paul himself is morally complicated. I've never seen it that way. I see it as a virtue. Being ride-or-die for the most powerful being in the universe is pretty badass. More importantly, she's Paul's anchor. Without Chani, he loses himself. He loves her so deeply that, in the books, he allows the universe to burn a little longer just to hold onto her for as long as he can. It's tragic, it's romantic, and it's central to the story Herbert was telling.
Chani is also just as much a product of the Bene Gesserit's religious manipulation as the rest of the Fremen. She doesn't possess perfect knowledge, and that's part of what makes her feel like someone who genuinely belongs in that world. Modern adaptations often seem reluctant to let prominent female characters have meaningful blind spots or unquestioned beliefs, as if loyalty or vulnerability automatically diminishes them. I think that instinct fundamentally changed how Villeneuve portrayed her.
Ironically, the new version strains my suspension of disbelief more than the original. In the films, Chani seems unusually aware of the Missionaria Protectiva and skeptical of the prophecy in ways that are never really explained. In a novel, you have hundreds of pages to justify a major character change like that and explore how someone developed those beliefs within Fremen society. A film simply doesn't have that kind of runway. When you fundamentally rewrite a character's worldview without establishing how she arrived there, it can feel less believable than the version from the books.
Just my $0.02. Fandom is strongest when there's room for different interpretations. We don't all have to love the same version of a character, but we can still respect each other's perspectives. Be kind to each other.
