I think it's more likely that a super strong, super fast, super durable, flying young woman in her late teens/early 20's who can punch holes through universes wouldn't need Strange's help in the first place. America had to appear weaker and less capable than Strange, otherwise why need him?
A couple years ago I'd have agreed about Marvel keeping things a little more grounded, but since Endgame we've had several characters brought in who are at the very least on the same power level as Thor, as well as stories that have been as fantastical and wild as it can get. We left "grounded" behind us somewhere between "evil robot tries to kill planet by throwing a city at it" and "army of super aliens invade world looking for magic rocks to accessorize a gold glam glove."
Ha! You're not wrong. Well, in my defense I did try to keep the review kinda short since everyone else had seen the movie already, and my thoughts on Strange himself are a little more involved.
I'm disappointed in his lack of a character arc. He basically goes from "I'm not happy; I saved the universe but lost the girl and people think I'm a dick because I let the Snap happen" to "I'm still not happy....but me and Wong will work through it together because we're BFF's." Wanda, and even America, got more of a traditional character journey than the main character did, and that's not cool.
However, I think there's actually a real interesting attempt to explore a different kind of arc via the Variants. We see the Other Stranges in a variety of situations and levels of mental health, all of which relate to 616 Strange's character arc in one way or another. It's like trying to put a puzzle together with pieces from different puzzles. Which is interesting, but it's not something that's obvious or spelled out and I don't know if it's satisfying either, because even though all this dialogue wraps around the idea of Strange's happiness (or lack thereof) it's still largely other people....even if those other people are also Strange.
And that's the entire character arc whether the Other Stranges count or not; Strange isn't happy with his life. That's it. He doesn't become Sorcerer Supreme, he doesn't get the girl or find a new love interest, even the destruction of Kamar Taj is glossed over (and they're rebuilding before the film ends anyway, making it a dead end for character development). Very little in his life changes until the very end when he picks up some dark witchcraft and an extra eye, but all of that stuff is left to his next appearance, it doesn't have any bearing on his story in *this* movie.
And there were a lot of distractions to pull our attention away from Strange too. The Illuminati, Wanda.....I feel like Strange could have gone through an amazing, huge character arc and people still would have walked out of the theater saying "Jim from the Office is Reed Richards! Wanda was insane and I'm pissed about it!" yknow?
