Don't want to spoil anything for those of you who arent caught up on the manga, but I've heard some hot takes regarding Eren and how the show is fash propaganda. Even though I see where these takes are coming from, I cant help but enjoy reading the manga.
I think the fash stuff is a bit overblown. I never read the manga though, just watched the anime. I get that the creator is a weirdo and the outfits look kinda fashy, and yes... there's a big strong military but it didn't set off any alarm bells for me and I like to think I'm pretty sensitive to fash shit. If I couldn't find the problematic message I don't think normies will be able to either, so I don't have any qualms about recommending it. Really good show IMO.
Edit: I guess what I'm saying is... yes some of the aesthetics are kinda fashy but I've not yet seen a convincing take on why the plot is fashy.
