just speculating (usually set design isn't accounting for anything beyond "looks cool"):

- Hazmat suites can contain climate control, and the Tuareg wear dark clothing as well

- Wyrding Module: In Lynch's words: He didn't want Kung-Fu on sand dunes

- No idea what you mean, but charging into battle has since been proven to be viable tactic by the Avengers, so it has to work

- Ornithopter refers to the propulsion, like a bird, instead of a simple helicopter; I'd have to watch Lynch's Dune so to see how those actually look like in his film; Villeneuve nailed them pretty well

- Same reason why the first Enterprise under Archer used fancier screens than the ones under Kirk or Picard; IMHO Lynch borrowed a lot of his aesthetics from WW1, and the Dune universe is surprisingly low tech anyway

- The navigator: A wild guess, I always understood it as a way to show the importance of Spice and Arrakis to the Guild when they had to send one of their Navigators to talk directly to the Emperor instead of using proxies

Re: charging into battle, I think the focus of the question was the pug.

Ok, I take Lynch pug and raise you by a guy carrying a shield but no sidearm then. The charging into battoe after breaking formation is similar in both cases.

If you're referring to something in the Villenueve Dune, I don't remember it in enough detail to know what you're talking about. And I only know the Lynch one from snippets and memes. :) I think I agree about breaking formation. Just once I'd like to see a movie that took battle formation seriously.

I referred to our beloved Cpt. America. For some reason we accept all kinds of absurdities from Marvel but call out other films dor much less. It's a film, a lot of stuff is just there to look cool. Which is a pitty, because those films that do shiw things like formations properly, e.g. Alatriste, still look cool if you ask me.

For Cpt. America this makes total sense...his shield is both a weapon and a defensive device, as demonstrated throughout the movies many times.

But carrying a small dog (a pug) while charging into battle? What exactly is the point? Where is the logic? Even if its the royal dog, when the compound is overrun by the archenemy of the duke, the royal family unaccounted for, the most effective weapons sabotaged, the last thing his most capable military commanders would think of doing, is saving the royal pet. And even if that was the intention, how does carrying it into the thick of the fight achieve that?

Yes, we accept absudities in movies, if they make sense in the setting. If Cpt. Rogers were to carry a pet hamster around in his pocket for seemingly no reason, while fighting Hydra, it bet the acceptance of this would be kinda low, Marvel or no.

Any story has an implicit assumption about the kinds and levels of absurdity you can expect. People get weirded out when you violate those expectations. Marvel, by virtue of their source material if nothing else, has set a much higher baseline of goofiness for their movies than most others. Whereas we all sort of know Dune was meant to be Serious Scifi. And I guess people who decide they like the Lynch adaptation have re-calibrated their expectations, and found the movie internally consistent on some level. It's all about audience expectations (and sometimes Hollywood ignorance/laziness, I guess).

There is a lot of truth to that. I just realized that I have a hard time to discuss fictional work with people, that base their criticism on a highly subjective view of "logic". Especially when that "logic" fails to be satisfied by actual, historical events and actions.

Heck, there was one guy that stormed the beaches of Normandy with a sword, internet meme culture considers that be cool. Reality had stranger things happening then a lot of fiction. And still people complain about fictional people in a fictional story not acting logical. As long as the fictional logic is in itself consistent, and that includes visuals and style of the fictional world, I'm fine with it.
