Harkonnen seems like a macho/strong society. So why would they drug the Atreides prisoners before they have them fight the skinnier nephew?
Whats up with the cartoonish evilness of all three Harkonnens, where in almost every scene, they randomly kill their own people? How can that possibly be an effective society? Once or twice out of extreme emotions and to show how evil they are via a common trope, sure; but like every single scene?
Why would the emperor come to Dune instead of sending his army and his delegates?
Why is the emperors army just standing in formation waiting around? They had no reason to do this- they werent expecting an attack, they JUST arrived, and there is a storm coming (they should have rather been focusing on creating temporary shelters).
Why did Paul fire nuclear missiles behind the army, instead directly at them? These bombs dont seem to be world-ending powerful, so strategic missiles against the well grouped army seems to have been a better option.
Why would the emperors army decide to go for a charge in an open field with sand everywhere, instead of falling back and creating a solid line of defense?
When the line was lost and Paul and his folks got into the emperors chambers, why would the emperors personal guards of like 10 or so decide to walk straight into the door that they cannot even see (because of lots of sand) instead of falling back and bolstering the final defense soldiers?
How come majority of these soldiers seem to not have any of those shields up, and the fremen are tearing through them so easily? The first movie made it very clear you have to attack in a specific fast-but-slow method to pierce those shields; its very clear the fremen are not fighting like this, nor were there any scenes that showed them being trained to fight like this.
Why would the other great houses not agree to the ascendency of Paul, when hes marrying the emperors daughter, and have spice production (a critical component of the entire galaxy) literally under his control?
Paul releases the fremen to go attack the other houses in the air/space. How do the fremen know how to pilot the emperors spacecrafts?
Why was Zendaya so bitchy about Paul using his messiah-like influence to bring the fremens together to fight the foreigners? It should be one of us that leads arc makes no sense since clearly they cant do that.
I didnt understand the significance of walking through the desert in that dancing way. Why walk like that? If its to avoid the worms, how come they dont always walk like that?
If the worms can be summoned so easily, be driven around like trains and devour everything in their path, are bulletproof, and arent harmed by missiles, why havent the fremens used it as a weapon?
If the emperor can very easily tell the south has human activity, how did the harkonens miss that?
Why was the emperor so quick to get rid of the harkonens (destroying Barons life support and his spine thingy)?
I think that was it when I was watching the movie.
