Denis Villeneuve's Dune: Part Two introduces notable deviations from Frank Herbert's original novel, particularly in character portrayals and plot developments.

In the novel, Alia Atreides, despite her young age, plays a pivotal role. The film adaptation alters this narrative. This change was likely made due to the practical challenges of depicting such a young character committing such act on screen (avoiding spoilers).

Additionally, the character of Chani undergoes significant transformation

Honestly I liked more, in terms of being close to the source, the one made by David Lynch. 🤷🏽‍♀️
