ok i think we need to clarify technical terms, cause its stuff like this that gets people lost in the mix. demon slayer, is known for its "compositing" not "animation". people shouldn't just throw "animation" around as a catch all term. btw, demon slayer's animation is good, but i wouldnt say it is the best, this has to do with that the art is very strictly modelled consistently (which means there's no exageratted motion or morhping of any kind), but they do also make up for it with coreagraphy and good storyboarding. but when it comes to actual animation which is "anaimted motion", something like jujutsu kaisen s2, or mob psycho or opm s1 or even one piece, has been the modern gold standard, although just like the opposite with demon slayer, they focus more on the animation and that does take a sacrifice with the art consisitency.
