While I see where you are coming from, not all examples are going to be 1-to-1. You can still be mass media, and still come off as pretentious. Insert certain shounen shows and certain anime that did hit mainstream.
Shaman King gets up its own ass about how much humanity sucks and how they are no evil shamans, but humans. All shamans (humans who can use and see spirits/ghosts) are either "misguided" or "misunderstood", humans that aren't evil are almost always portrayed as impotent at best, or card carrying evil at worst. There is no subtlety and makes the writing come off as simple black n' white with no grey areas, or only "grey areas" for the shaman characters only. The message comes off as even more hypocritical, because shamans are "in tune with nature" generic bullshit, and the main villain we're supposed to cry and feel sorry for is a complete homicidal psychopath. This is mainly in the manga version and what I am assuming is going to be in the second anime adaption on Netflix. Which is going to be more true to the source material. Hao Asakura is an unsympathetic asshole who has killed over at least 1,000 people, human or shaman alike. It sure as hell was not for the benefit for nature, shamans, or the fucking Earth! We're supposed to feel bad for him, because
he lost only three people in his entire life, but more so due to the lost of his goddamn mommy. He's caused way more pain and suffering than all of humanity put together. What worse is that Hao gets what he wants in the manga, though he does not destroy humanity. He still a petty dick, we're supposed to agree with, but most readers don't or feel the author goes overboard in trying to sympathize with him.
Naruto has almost the exact same problems with characters like Sasuke, Obito, and nearly the entire Uchiha fucking bloodline and clan. I'll just let this guy speak for my rage. Naruto gets pretty pretentious with its many broken messages. I am glad I stopped watching after the Sasuke leaves Konoha arc.
