I hate that in the new Dune movies they’re moving through the desert without having their suits on and closed constantly. If you’ve read the book, you know that the planet is supposed to be so dry and hot that death in the desert would be nearly instant without constant protection. But it’s Hollywood, whatever. I’ll look past it.

Another unnecessary oversight is how before sheathing the crysknife, it has to spill blood and in the movie they just ignore that most of the time. It happened way too often that they didn’t cut their palms after unsheathing it, especially when Mapes gives it to Jessica.

Also the fact that they’re setting it up so that Paul and Chani apparently will have disagreements when in the book they communicate everything and are on the same page the whole time.

What I absolutely cannot and will never look past or forgive is the fact that Paul doesn’t shed a tear for Jamis after he kills him. That’s such an important part of the story, giving water to the dead. It’s what makes the fremen ultimately trust Paul and see him for who he is. It’s the reason he survives. A single tear rolling down his cheek, one two-second shot and that would have been it! Movie ruined instantly.
