I'm doing all the main and side missions while ignoring radiant or filler stuff and it fuckin' sucks. I played Fallout 4, which I consider mediocre at best, the same way and remember having a MUCH better time. Starfield is so utterly boring that I'm actually kind of fascinated by it. It's immediately obvious the first time you set foot on an "unexplored" planet that the entire allure of Bethesda games since at least Oblivion has been abandoned. There is no intricately designed open world here, just copy-pasted garbage.
Never mind how the world feels even more disjointed than ever. There was apparently an interplanetary war lasting years between a fascist industrialized space society and checks notes 20-30 cowboys.
