The only thing more foolish for them to do, is for them to take a vow of silence.Let's not fool ourselves. The strict "don't remove the helmet" rule is a literary device to make a character seem mysterious and to make seeing the character's actual face a dramatic event.
That's it.
We can set that aside for the sake of the story and accept that it's a cultural thing but it borders on ridiculous to ask the audience to ignore the impracticality. They could have made it clear that the helmet can’t be taken off in the presence of theirs but, no. They’re making it a big deal that it’s EVER off by the free will of the wearer … (I bet you a soda that they’re setting up a scenario that it gets taken/knocked off by an opponent later this season)
The Mandalorian upgrading his armor wasn't a problem despite getting a new helmet?
Equipment in the Star Wars universe breaks all the time but we're to believe the system in a Mandalorian helmet never do?
Hygiene?
Nutrition?
How does Din Djrin have short hair and trimmed mustache?
Children get helmeted when they're young so the helmets somehow resizes itself as they grow?
I get it. Culture is central to the character(s). This is just a dumb and lazy way to express that.
All that said I’ve been more than willing to look past it when it was just an occasional reference but so far season three has been ALL about the damned helmet. If the over/under on how many times the word “helmet“ gets used this season is 1,000 … I’ll take the over.
I think you're over thinking this. We're talking about a made up alien civilization, and I'm just going to enjoy the story.
