Larian really, really needs to go check out most any other modern Turn Based cRPG and see how they handle movement. PKM has a fantastic mechanic for dashing that never once felt clunky.
It's not that "fantastic", really. Serviceable, I'd say. And based on a different rule as well.
In PF:KM dashing ("charge") is a default action of any melee, it doesn't prevent you from attacking but it must be in a straight line from your starting point and done before deciding any other move.
Here's is just extra movement made sacrificing your action (unless you are a rougue).
Overall, in terms of mere presentation, I'd say that with all its rough edges that needs to be worked on, BG3 is already leagues ahead of Kingmaker when it comes to art, effects and animations.
And I liked KM a LOT (after the turn-based mod became a thing, at least).
