I think another issue is that when telling the Avatar story, all the main characters are necessarily children, and the themes of the show require some really hefty acting chops to deliver lines convincingly.
I can’t fathom why they didn’t tell a new story in the Avatar universe, or at least remake TLoK where the main cast are a bit older.
Stremio & Real Debrid is soooo much easier than the self hosted approach, and is a piece of piss to set up
