This shift seems to have happened from the mid-90s on, arguably, but it is very noticeable since maybe the mid-2000s. And you see it in everything, from kids’ shows to adult series to films.
What I mean is, in classical literature and fairy tales, generally supernatural beings want to become human. Gods and demigods don’t, I guess, but most other beings, and indeed most anthropomorphic animals, do.
This carries over into most early and mid-Disney stuff, from The Jungle Book through to Tarzan and The Little Mermaid. Obviously most of that is based on earlier stories. And then..? Shit went the opposite way.
First we had Felix the Cat and Brother Bear, and obviously “mutants” in comic series, and it seems to have ever-expanded from there, to the point where vampirism and lycanthropy for example are seen as less a curse or punishment, and more “a gaining of powers”…
One good example, perhaps, is to compare the original Grimm fairytales to the ridiculous tv show they made, supposedly “based” on those stories. Or Supernatural, similarly. Or Prometheus vs Alien. Or, for another slant, Bicentennial Man and AI vs something like Humans or Deus Ex Machina…
To me, at least, this is a very noticeable trend, across both fantasy (in particular) and sci fi, and it seems to carry with how obsessed people are now with mutilating their bodies, “transcending” gender and race and all that sort of shit…
Also noteworthy that we’ve gone from curing disabilities, in fiction, to portraying becoming disabled as a positive thing, and a form of “superpower”, rather than the thoroughly net-negative experience it usually is…
They even do that shit in kids’ programming, now, too…
So yeah, just something else be noticed and have been thinking about…
Bran Stoker be rolling in his grave…
I guess you could argue this all ties back in to our desire, now, as a society, to feel “special” and “different”, and to be “recognized”, but I do not see it as the sign of a healthy, self-respecting civilization, imho…
As a side-note, I hate how the delusional fad of tannyism got mixed in with sci-fi inspired transhumanism. With New Age, we got ritualistic women with make-believe magic beads. Right now, we got some severe cognitive dissonance and willful ignorance going on with the physical realities of genital mutilation. We've got to accept it, else be charged with the high treason of bigotry. The real societal upheaval when we have the biomedical technology, or AI+robotics, to transcend modern humanity has no substantial relation to the barbaric, pseudo-scientific fad Western society entertains today. To repeat for emphasis, sci-fi or fairy-tale sex-changes thoroughly alter the body's composition to actually change the person's sex.
