The scope and vision cannot be grander. And Starfield indeed looks grand from the first minutes. The various mechanics and systems built into the game, from spaceship building to planetary exploration, are truly amazing, enough to fill multiple decent games.
But that's where the positives end. Starfield produces almost no gel, either in the form of a good story or cohesive world building, to hold its different parts together. The grand scope becomes pointless and bleak when there is no narrative to drive it. The various mechanics do not talk to each other and start to feel redundant very early. The saddest thing is when you push yourself to invest in some of them and they are proven to be redundant by the end of the game.
Bethesda seems to think that just because it's the first universe in 20 years for Bethesda (it's Bethesda!), players will just stick around for hundreds and hundreds of hours until they eventually truly appreciate all that's built within this grand scope. That's hubris. I felt a tinge of nostalgia I completed the game. Then I immediately deleted it and all my saves. What a disappointment.
