A masterclass in book-to-film adaptation. Obviously, the two biggest changes they made to the book were Alia and the ending with Chani, and though both are big risks, they make sense in of translating something into a film. There is no way you could cast a child actor to play a character as all-knowing and physically adept as Alia Atreides, and Paul's betrayal of Chani gives this film its "I Am Your Father" moment it needs, as a turning point the entire film hinges on to punch the audience in the gut. If anything, they – alongside other original (inspired) creative decisions like portraying daylight on Giedi Prime in desaturated black and white, or the tease of Feyd's unborn child – reinforce the characters and the timeframe in which Villeneuve chooses to set his version of Dune and set it apart from the source material as its own thing, which is what every adaptation should strive for. I'll have plenty of rewatches to dive into every little nook and cranny of this film that I absolutely adore, but for now, I'll just say that ending your massive blockbuster science fiction epic on such an intimate close-up takes massive balls. Above all, these films represent an uncompromised vision, and I'd be hard-pressed to find many I've enjoyed in recent memory as much as Dune.
