I saw it on Monday. I think it was an interesting way to move Thor's character forward. The scene with Dr. Strange was well done, and tied in very well with the end credits scene from the Dr. Strange movie. And Tom Hiddleston playing that up with the line about falling for 30 minues was great!
The inclusion of the Hulk in the story was a nice way to pick up his story from the end of Avengers - Age of Ultron, and I really liked the tie-in with the Quinjet's log where Black Widow tried to talk Hulk into transforming back into Banner. The humor between them seemed pretty genuine, between Thor and Banner talking about their fight... per Thor's recollection. And then Thor calling Hulk a moron for fighting Surtur? That actually elicited a gut laugh from me!
Cate Blanchett was fantastic as Hela. I think she was reasonably well developed as a villain. Her presence alone was pretty amazing. And she dispatched the Warriors Three pretty fast. Her story having been intertwined with that of Odin certainly gave Thor a lot to think about in his path forward.
I've seen some people describe the humor as broad. I don't know that I'd agree with that assessment. I certainly found it to be enjoyable, and I think that the Sakar angle played up the fact that Asgard was part of a larger interstellar landscape. And that, along with Loki's actions in the weapons vault, will seemingly tie into where the MCU will be going with the next Avengers film.
