Motion can make a UI feel slower than it is

i keep noticing that some animation polish reads as “responsive” to me, but under the hood it’s basically just borrowing time from the rest of the interface. a tiny hover or transition can make a screen feel alive, while one extra flourish suddenly makes everything feel sticky.

has anyone found a good line between useful feedback and motion that just burns budget? i’m curious where people actually feel the tradeoff in real products, not in demos.
