Just saw Dune yesterday.
Pros: It's honestly not nearly as woke as the race swapped characters would suggest. The cinematography is great, and I think the cast was well selected (unnecessary race swapping aside). They did a great job of designing the costumes and the spaceships too.
I haven't seen anything in the way of woke pandering and politics thrown in your face, but Zendaya doesn't really do anything in this movie so who knows about the next one.
Cons: It's a bit confusing who/what everyone/everything is if you haven't read the book.
You will have to use the bathroom after watching it.
How it's portrayed is up for interpretation. The movie is going to stylize it in a way that makes the fights more visually dynamic.
I don't think Herbert described the fight choreography in enough detail that you can really say for certain what the fighting looks like. What we do know is that each combatant is armored (via Shield tech) to the point where the only way they can actually hurt the other opponent is by getting in close and delivering slow, precise & deadly strikes. This is similar to European knights whose armor was so effective that they were mostly only vulnerable to stilettos at vulnerable points in the armor joints.
A better example would be a high-school wrestler. If you're fighting with someone hand-to-hand with knives, grappling techniques are essential.
