if it's more about the emotions and character development, they ease off on the length and animation of the fights, which both puts the narrative in greater focus AND saves them budget for stuff like, say, a new cure's debut next week
comparing it to trigger isn't weird, trigger's one of the last studios besides toei to really put emphasis on the kind of animation that creates kineticism through restrained underuse of keyframes and classical bounce and squish to create a sense of momentum and weight instead of throwing keyframes and 3d environments and post-processing effects at it
a lot of anime studios no longer teach newbies how to utilize classic limited animation techniques because they're budgeted "enough" and expected to output "fancy"-looking enough productions that they can't set aside time to and don't employ anyone who still remembers how to do it
there's a few sub-studios under sunrise and bones that do provide instruction in it, toei's kids' show department reliably offers the experience, science saru, p.a. works, and trigger. and kyoto animation uhhhh used to - it was one of the reasons kyoani reliably were so much better than their imitators
my first precure was tropre so i'm ceaselessly impressed by the way hiropre makes its budget actually work okay
