I found the film quite beautiful to watch, but a bit too long and slow. They fell into the trap of picking a good stopping point for Part 1, and went too far to fill up time. I appreciate establishing the positive influence Leto and Duncan Idaho, but 20 minutes of Paul and Jessica meeting up with Kynes and Idaho could have been wrapped up during the attack. I know they wanted to avoid the opening "What You Need to Know", but that is the danger of trying to adapt a work like Dune. Entire historical points are provided in chapter preludes that people who have not read the book really need to know. My wife was still not clear who the Emperor was by the end.
I believe Zendaya suffers from poor writing and directing in the Spider-Man films. She is excellent in Euphoria.
The fight scenes are good, and they did a nice job showing the four or five Freemen take out a large number of Sardukar, but again, the film failed to establish how jaw-dropping a feat that is. Sardukar are established as unstoppable killing machines in the book, wiping out entire armies with a handful of men.
