Dandadan intro and its lack of FPS and sharp lines: https://www.youtube.com/watch?v=a4na2opArGY
Animation doesn’t feel fast if it’s too many FPS or too steady, anyway, ironically and counterintuitively. You can’t do everything on the ones and twos.
To your point about Dandadan’s intro, it’s jam packed with references, which is another kind of skill in and of itself:

Chainsaw Man is in that same vein, and is another Science Saru production. I’m looking forward to seeing what they will do with the Ghost in the Shell franchise next year.

I get what you mean though regarding Dandadan’s animation style; it has a very hand drawn manga vibe, and the detail is minimal yet finely balanced against the overwhelming amount of noise and visuals. It’s like a slapdash superflat.

On a side note, as an anime fan, MBS is doing great work lately. I liked Witch Watch much more than I expected to, and that’s a much better show than the genres involved would lead one to expect.
