He did, and Love had Stormbreaker, so... Yeah. And he has short hair again.
I actually fucking hate short-hair Thor. But it's expected. Chris has said more than once that one of the things he doesn't like about playing Thor is the long hair and that one of the things that got him to come back was when they said he could cut it off. I figured we were getting short hair Thor as soon as the rumor hit that Chris was coming back for at least one more appearance.
Mjolnir is still my big question mark. Maybe Doom stole it? Who knows.
I do not think Thor's MCU arc is finished until he ascends to the throne and fully takes on the responsibility he has. I will also note that Hemsworth was mentioned a few months ago that he realized they went too silly with Thor and that undermined the character. I am suspicious that scene of him praying is after Love has been taken, or he had a vision about it...
I kind of always expected Thor's arc ended when he realized he doesn't need to be anything other than what he is. It seemed like they'd kind of ignored the 'there always needs to be an Allfather' thing. Cool that they seem to be returning to that idea again, though. I do have to wonder what a fully powered up Thor looks like in the MCU, since just full THOR powers Thor in Ragnarok was insanely badass.
Also: I think it dilutes the heroism when it is personal and about kids. Cap fights evil because he is Cap, not because some guy threatened his kid and HOW DARE HE!
What if, and hear me out on this; the heartstring they're trying to pull in the actual film is that Cap has a kid now and has to leave them to go do the right thing. To go fight a fight he might not return from, because that's what Captain America does even at any and every personal cost. Maybe it's not a motivation for Cap at all, but a motivation for the audience to want to see him survive and go home - when most audiences are kind of usually okay with heroes making heroic sacrifices.
I still think that's the MAJOR reason Tony had a daughter; they could have manufactured any number of motivations for Tony's behaviour. They wanted the AUDIENCE to be more upset by the idea that he sacrifices himself. -We- wanted Tony to go home to his daughter when this was all done. Without her, we would probably be generally more accepting of him just dying to save the world. Sure, why not - that's what he's there for after all.
That in mind, I'd also just generally caution that we know next to nothing about this film. There's little value in getting deep into the weeds on what certain elements of the plot MIGHT be. Kids seem to be important. Are they important to the characters, to the plot overall, or just to the meta narrative? Who knows. The film industry has a now storied tradition of not even being honest in their trailers by including dialogue and scenes that aren't in the movie, or are edited in a way to be very different in context from how it goes in the movie. I just don't think we have enough to go on right now to worry about much beyond the general complaint of 'going back to the well and resurrecting characters that already got endings.' That would be a very valid concern.
