If you are only thrilled by a movie because of its middle and mid-credit-sequence cameos, are you really thrilled? If those two were taken out, this would be a sub-par effort because all of the nuance and lessons of WandaVision were sacrificed in order to create a decent horror showcase.
SECOND VIEWING REVISED THOUGHTS:
“In this movie, he makes a tiny little journey from being a very proud superhero to being someone who learns a modicum of modesty and learns that other people can be trusted, too,” [director Sam] Raimi says. “He’s not the only one that can do the job. It’s about coming to understand that others have worth and he’s not better than everyone.”
The film was better the second time when I figured this out and accepted that the above was its only thematic thrust. My real problem with the movie is that it wasn’t worth stomping on the character nuances of its best TV show to date to get there. Strange’s growth comes at Wanda’s expense. We’ll see if the Marvel Master Plan is worth this.
