Art is in the eye of the beholder ultimately. People been saying the same thing about art since the dawn of art, NFT are just newer so not as accepted as abstract paintings just yet, but eventually it seems we'll end up there.
What? Moving film, even CGI film, has been a well studied artistic medium for nearly a century. The mechanisms to analyze and critique this kind of art exist. The novelty here is the mechanism of attributing ownership - not the piece itself.
Nothing to disagree with there-- but in terms of what's actually possible with animation / 3d graphics, this looks like it was done in paint (and I'm questioning why anyone would pay money for that standard of work)
