Finally got to see it aswell yesterday. And very much agree with you that it was amazing.

For example, the time Paul and Jessica spent in Sietch Tabr felt so quick, without having a reference/barometer to let audiences know how long it took for them to turn the Fremen to their side and Paul and Chani’s relationship to develop. This took years in the book, and book readers will obviously know that, but I feel like non-readers will complain how “fast” it happened. It also doesn’t help that since they cut child Alia in this version, this means all the events in the film happened in less than 9 months, which is pretty short for someone to integrate into a planet’s native population, train in their ways, and rise up as a messianic figure for an entire planet.

Also having read the book i had the exact same impression. It also meant that the birth and death of his first child with Chani was cut, which i guess wouldn't have fit into the movie anyways with so much going on, but in the book did add more emotions.

As far as minor criticism goes i tenatively agree with another comment in this thread that the soundtrack might have lacked some melody.

It's been a while since i've read the book, but in my memory the death and destruction paul forsees unleashed through the jihad seemed much more intense than what we got in the brief visions in the movie.
