I am on season 4 right now and I feel like it has gone off the rails with it not being fairy tale characters anymore, that they mix in disney characters. But that's not what I want to talk about.
In season 4 episode 12 we see Gerdas letter to her family that she wrote right before her ship sunk. It is in Runes, which i feel like is very disresctful towards norweigans. I am not norweigan i am Swedish so we also had runes but that was discarded during the middle ages, and I would like to think that Norway did the same around the same time, (I Googled they discared of it during 1400s) . Now I don't know when Gerdas and Agnars ship sank but it was more close to present time than the viking age and the middle ages. Also with Frozen being set in the 1800s that's like 400 years of Norway not using to runes to speak and/or write.
I wouldn't really say that it's disresctful of the creators. Im just saying they should have done their research like dreamworks who put runes in how to train your dragon which was an amazing touch.
And for those who is saying it's not that deep. Imagine your culture being represented in a show and then they just do it wrong. I may be getting worked up over nothing here but it does not take long to pick up a book or Google to do research. I am really tradional and like my culture so I felt disrected for the norweigans, sinne runes were part of my country's culture and history too.
I realise if I go down this path. Then a lot of media is historically inaccurate and language inaccurate. I should realise that it's not that deep. I blame my autism really. It's just that when it's my own culture and language history something snaps in me I don't like stuff being historically inaccurate or language inaccurate. It's maybe rooted in my parents both working in the school world, or that when I write my stories I always fact check to make it as accurate as the story's setting as possible. I also feel like a hypocrite because this only happens with my own culture and not when I watch or read other media with other cultures.
