Really? I assume we're talking about the Avatar with blue aliens here, not the one with magical martial arts.
When I think about eutopia, I usually start from a sort of idealized hunter-gatherer society too, though the one that first comes to mind is something much different that I read much earlier. But Avatar never seemed that eutopically optimized: too much leaning on noble-savage tropes and a conspicuous lack of curiosity and ambition. And aside from the fringe that you get every time you put sufficiently sexy nonhumans onscreen, I'm not sure I've seen anything that matches what you're talking about.
If there's curiosity and ambition, you'd have to portray a snapshot of a eutopia rather than staple image. Furthermore, if it keeps changing, there are going to be mistakes, though one would hope recovery from them would be relatively quick. And, of course, if the science/tech keeps improving, then it's rather hard to imagine the details.
