I liked the movie a lot while watching because of the humor, although sometimes it felt a bit unappropriated for the situation and took the gravity of the situation which I was used to in the other Thor movies.
I think the quality of this movie is in the brilliance of the performances and the colorful and convincing world building.

To the characters, their was not one character in the entire film I disliked Hella is a force every time she's on screen and she's just so unapologetic about her prowess, also the combo of Hulk and Thor with Valkyrie (and some Loki), just works so well.
As you mentioned the world's so detailed it makes fun to just look around. Not to forget that their some nice messages about growing up and responsibilities.

Nice review ! :)
