The problem with japanese live-action is that they try to transpose the source material (manga or whatever) as is (dialogs, character designs, etc), but this will usually be kinda cringy… You mentioned Alice in borderland which I watched and enjoyed, but that is because of the story, while It was just barely watchable on every other aspect for me (ofc its very opinable)

Youtube actually experimented using a neural upscaler on shorts a while back but they got some backlash and reverted it https://www.androidauthority.com/youtube-shorts-upscaling-experiment-3591230/

honestly I don’t think they’re going on a witch hunt here, I think they’re putting this in their term of use so that they can take projects down if some issue arises…
