Maybe they didn't go east enough. Like a lot of Iranians and Persians aren't necessarily dark skinned. I am disappointed, however, with the lack of prominent black characters in the show - I think they could have tried a little harder.
Iranians and Lebanese folks are pretty much white looking, but they have their own languages. They didn't speak English with an English accent like the Braavosi bankers, Meliandre, actors, and Qarth inhabitants did.
Jaqen Hagar and Kinvara spoke with an accent but I think it was because of Valyrian.
I agree with you about the black characters, though. That's one of the reasons why GW is my favorite character; there just aren't enough black characters. I wish Jon would think of the idea of going really further south to get more men. "Let's go to Sothoryos. We've never been there before, but they are people, just like us. Wildlings living North, and Sothoryans living all the way south, we are living people and the winter war is a threat to us all."
Of course it would be a long travel down but this show has shown how fast people travel so it would've been worth it. And it would bring in a reason to have way more black people on the show.
And also I think with the language: you certainly would not want the Dothraki to be connected directly with a real world culture. Their whole civilization revolves around raping and murdering - the backlash if they spoke Arabic would be catastrophic.
All of the Dothraki weren't barbarians though, some of them were level headed and there were organizations and civilizations in Westeros that did the same things, the Ironborn for instance, and Tywin Lannister, ordering the mountain to do to villages exactly what you just said the Dothraki would do.
Honestly, it just makes it seem like English and the whole central white medieval theme that a lot of the lore is based on is more important than everyone around it. Which can be true I guess but it undermines the other people around the setting. English is a real language, it's a language on the show; Arabic is a real language, therefore it could've been a stand-in language on the show.
Edit: Are we sure that the unsullied held against Euron?
eh, it's pretty unclear at this point. i heard that the Unsullied boats that Euron was destroying were empty and now the Unsullied are trapped there...that's just one guess. Euron not being around for much of the season is going to make his death feel not so paid off.
Edit 2: Also English being "the common tongue" is a basic trope in fantasy stories. I may be wrong, but I think Lord of the Rings did a similar thing. The different races had their unique languages and dialects, but everyone basically understood English.
Nah you're right, Lord of the Rings did the same thing but I'm a much bigger fan of Thrones and I was just a kid when the LOTR movies comes out.
I get that in high fantasies English being the "common tongue" is a common trope but if you have to invent languages for all the other cultures, doesn't that make it seem like the white people's language in these stories is superior if they just use the real-life most spoken language, while inventing languages for all the people based on all the people surrounding the white people?
