The Monogatari series is probably the best example of this with a lot of scenes in Bakemonogatari and some of the following seasons having little to no animation but being so stylised that it remains visually interesting. Studio Shaft also tends to do this with other shows. When there’s a long dialogue scene or if they just don’t have the staff to do high quality animation they’ll just throw in a weird camera angle or have the scene take place in bizarre setting.
It usually ends up being interesting anyway. Whatever trick they use gives the viewer something to look at and think about in place of animation. Sometimes it’ll create a sort of feeling that can’t be put in words like the iconic desks stacked together for literally no reason:
You would be reaching far if you looked for meaning in everything they did but it ends up looking good nonetheless.
This happens even in other mediums. The Pop Team Epic manga often reuses the same simple drawings on a page to keep the focus on the punchline. The manga author and illustrator Panpanya also does this with their simplistic character designs to draw attention to the amazingly detailed settings.
In the video game industry, a game might be created with a large budget and an army of developers behind it and still come out bad while a solo indie game developer can create a masterpiece.
Anime like Violet Evergarden also fall into this trap of putting way too much effort into the animation while the other aspects don’t hold up as well. Animation can’t save a mediocre script. It should work in harmony with the other elements to get the point across.
I am by no means advocating for less animation in anime, I just wish that more shows would focus on their aesthetic cohesion and not just add more of everything while adding nothing.
