I'm starting to really appreciate AOT.
I'm just on my first rewatch and it's making me really appreciate it. Don't get me wrong. I loved the show now just as much (and more) as I loved it on my first watch. But I was younger at the time, so I was more so watching for the hype moments and fighting.
Now on my rewtach, with a much mature outlook and I'm noticing their attention to detail, world building from their economics, poltics, history down to their fictional science.
I realized this appreciation especially at the episode when Falco and Gabi are taken in by Sasha's family, and one of them make a comment about her father's accent resembling a southern Marleyan's. And the explanation I found was that they were something of a remote community that were so secluded that they retained the accent.
It's honestly rare to find this much dedication and attention to detail in something as miniscule as the accent of a supporting character's parents. My favourite aspect of a piece of media is usually their fictional history. How much and how deep they can contextualize their world and still keep the disclosed history relevant to the present plot and AOT does that perfectly.
