Whenever the topic of animations come up, people bring up PBR, which I've always found strange. I don't want intensely long and detailed animations of pokemon winding up, charging a kick, rushing towards the opponent, kicking them, and then running back like they do in PBR. I appreciate how cute it is that they were able to make unique kicking animations for so many pokemon in Stadium, but I think it's reasonable that its not feasible when you have 930+ pokemon. That said, atleast stuff like the cinderace line should have a short kicking animation, it's a footballer after all.
I don't think the animations in stadium are much longer than their counterparts in the main series, for the most part they're just as bad. I'm sick of seeing the same dynamax/ z move/ mega transformation cutscene every battle, it makes me dread playing online on the carts.
In my opinion, animations should be snappy, not "detailed", they should convey the gist of what the attack is in a short time, while also looking appropriate. The PMD games, Pokemon GO and Pokemon Showdown do a pretty solid job of achieving this.
