In my case, it all comes down to managing expectations. As someone who played all Bethesda games since Morrowind (except F76), I know exactly what I can, and should, expect from them - which is a great deal of exploration, underwhelming main story, fun (at times) side quests, fantastic environmental storytelling, no impact of your choices on what's happening in the story and dull NPCs.
If I get that, I'm perfectly fine with it. I know I'm probably in minority, but I really liked Fallout 3 and 4, not for the good story (which IMO was in both cases better than what Bethesda offered in Oblivion and Skyrim), but for the sheer joy of exploration.
I obviously haven't played it yes, but if Starfield is able to offer the same enjoyment I had while playing Fallout 4, it would be all I need from this game.
