He lands from such a great height and his knees don't even bend.
I have the impression that smooth/realistic animation and snappy controls are to some extend mutually exclusive, with most Nintendo games going for the snappy controls.
Looking at the prime examples of halfway realistically ainmated characters, especially the cinematic Naughty Dog games and the Rockstar games, the characters move pretty realistically, but controls as a result are highly indirect. Nice to look at, but hitting a button.e.g. for jumping or interacting with something is more a wish for your character to execute something, as the animation will take their precious time to blend the various actions. "Please climb up that ledge, whenever you have the time to move your body and all your limbs into a position where that's ok, thanks. Please turn around, but take your time, I know your body won't turn round as fast as I can move the stick."
In contrast, any games where snappy and direct controls are prioritized will invariably end up with janky animations. Taking as an extreme example PC first person shooters. Characters turn as fast as you can hurl the mouse. Characters accelerate from a standstill to full run practically the moment you hit the "forward" key. It wouldn't
feel right if they didn't, because of the artificially introduced delay between your input and the execution. From a first person perspective, you hardly bother what your character model does with the rest of it's body other than the arms.
Now, Zelda is a 3rd person game where you see the animation, which however mostly goes for snappy action execution upon input. If they did "realistic" or "smooth" animation, the game would feel very much different to play. Far more indirect and less snappy, because it would have to leave room for animations to play out and blend into each other. Personally I can live with the twitchy animation and snappy controls, as I don't value the cinematic feel of the Naughty Dog and Rockstar games so much for actually playing, but rather for watching those games.
