Saw Dune Pt 2, which I didn't seem to enjoy as much as I did Part 1 tbh. So I have questions regarding the characters in the novel vs Pt 2 movie.

Where the Harkonnen's more prominent in the novel than in the movie(s)? I seem to remember they had a larger presense in the 1984 version. Seems like they were supposed to be the major antagonists and I felt they didn't have much screen time.

Was Paul's character transition after drinking the Water of Life depicted accurately in the Film as in the Novel? I feel he becomes almost a completely different person after drinking it.

Any help is appreciated!
