Iron fist has to be dead last, what a steaming pile of garbage.
Loki is so over the top it invalidates so much of what we have already seen. When you have an organization that keeps infinity stones in an office drawer it makes it hard to care about all of the sacrifice to deal with Thanos.
Most of the rest seems solid
Eh, it's akin to having the US military exist, and still making movies about some drug dealers threatening cops in New York. Yeah, if it came down to it the US military could probably blow up all those drug dealers, but that's not their job.
The TVA can, sure, completely undercut any personal growth any character has by just stepping in and unwriting that branch of the timeline. But they don't care, and Marvel won't make that happen because they're not in the business of making nihilist films. As avant-garde as it would be to have had Endgame end with some time agents showing up at the start of act two to erase everyone and force the world to remain blipped, that's not popcorn cinema.
And in-universe, I assume there's some justification like . . . if not for Scott Lang proposing a ludicrous 'time heist,' no genuinely smart person like Tony would have ever taken time travel seriously enough to have the epiphany necessary to make it possible, and even then, only in the universe where Tony then
dies very quickly does time travel not create a huge Swiss Cheese paradox of the multiverse,
and the shared suffering of the whole cosmos losing people and then getting them back avoids some super-war, which lets reality last long enough for Kang to arise, which is why after he makes the TVA he ensures that this particular ludicrous reality is the one that is considered canon.
In all the other millions of possibilities -- including super simple ones like Star-Lord not bopping Thanos so they can get the gauntlet off him -- that unfortunately leads to some universe where Kang doesn't reign supreme, so he sent his TVA agents there to erase it.
That was why Dr Strange kept seeing reality getting destroyed in all the futures he looked into. Not because Thanos is that hard to beat, but because Kang needed Thanos to win, and then for time travel to happen, and then for Tony to die saving the universe.
Like, Buffy saved the world. A lot. But the best episode of the series wasn't about saving the world, but about her mom dying. (Okay, the best episode was The Zeppo, which I suppose technically
did involve her saving the world, just not as the main focus of the plot.)
