The Damage to the Marvel Studios Brand

Guardians Vol. 3 was supposed to be the first movie out of endgame, which would have made the post-endgame era kick off in such a strong Marvel brand place. But because James Gunn was briefly fired, etc,. it comes out years later and so the question that I have is if this movie is a hit or does it feel like it's just burnishing James Gunn's reputation as he leaves Marvel to go run the competitor DC? There's still a lot about Marvel that needs to be contextualized and characterized, I think.
