okay, but unironically i do think "isekai" is a term we should absolutely be applying to media outside of japan/the broader east. i think calling this a "time travel story" gives a different impression as to the amount of control there is in the time travel happening, and "science fiction" makes it sound like the time travelling is technological, when it's instead, at least thus far, functionally magical/supernatural (even if not explicitly described as such). i would definitely categorize it as both of those things, but it is first and foremost an isekai in my mind.

frankly i just don't get the disgust i've seen when i dare to call things like jumaji (the new one with the videogame) "isekais" especially when this disgust often comes from the same people who call random western animation "anime". i guess it's because the people who i see react negatively like that have only ever interacted with shitty japanese isekais like sword art online or whatever, ones which rely heavily on a certain set of tropes not even inherently unique to isekais, so they think of isekais less as the "often-unwillingly whisked away to another world" narrative that to me binds them together most strongly, and more... sword art online, lmfao
