The issue with Super is quite a bit deeper then that actually. Unlike DB or Z, it’s a completely original product, meaning they don’t have Toriyama’s storyboards as a basis to expand/adapt. Add in time constraints due to rushed production and the actual key animators don’t have enough time to compose fight scenes while doing corrections of other animators’ shots and you got a mess that until recently seemed flat out afraid of having fights.
Another problem most people don’t talk is the character designs. Look at these:
Tadayoshi Yamamuro (character designer from middle of Android arc until today), Minoru Maeda (Original character designer for the series since day 1 till he was replaced by Yamamuro) and Toriyama’s base.
Unlike Maeda, Yamamuro has tons of lines and stiff angles. The stiffer your drawing is, the less you can deform it to create actual motion. And when you strip the details down to make it doable on a normal schedule…
Yamamuro’s art is harming DB, regardless of how “iconic” it is. The only time we get good motion in the series is when the animators completely ignore his style, like here:
You can say whatever you want about the art, that’s purely a time constraint, but it actually moves well and has strong sense of power behind it, even without the sound effects.
