Visually, I have experienced that detail alone can captivate me during a scene. Its like when we admire a particularly beautiful piece of scenery or exquisite character close up where motion is absent, and I don't miss it. Shortcuts are always there, but there are ways to minimize the impact that we're so used to seeing now (panning shots, shaky-cam, cg effects like lens flare) our minds just kind of fill in the blanks. The closest we're going to get to full time Sakuga are the movies because they have the budgets and time to focus on animation holistically, instead of literally committing production to air before most of the future episodes are finished.

Ironically, I wonder if our appreciation of fluid animation would much wane if it were the norm. When I power through CG anime, the fluidity is getting there, but the perspective just isn't the same, artistically, and I never seem to enjoy 3d character designs quite like the cell based ones. Case in point, the Airplane/Dogfight show from last season: I actually did not recognize main cast characters when they made their 2d debut for minutes, in spite of thinking to myself how much I liked these character designs and wondered why the show waited so long to introduce these (new?) characters. Characters would morph, for seemingly no reason, scene to scene between planes of reality... I'll take the jank of 2d animation if it means... 2d animation.

Rant aside, the Youtuber Mother's Basement just dropped a light examination of animation quality and production incentives as viewed through the lens of One Punch Man season 2 "Does Anime Need Good Animation?" suggesting the monetary investment wasn't worth it to the IP holders. For an opposite take, (and opposite end of humanity), another "anituber" Digibro put out a video a few years back titled "Stop Blaming Budget For Animation Quality! [Rant]" which boils down to not budget, but time+talent equals quality. Cases could be made both ways.
