1. Loki has the Tesseract after New York.
That's a hanging loop to close off. Presumably in the Loki TV series?
2. The final scene.
Yes, I know the loop can be argued as technically closed, Steve returns, assumes another name, stays out of the way; Peggy and he get married and have kids, and he pretends to 'die' at some point so when Peggy meets Steve-woken-from-the-ice, she's lived their life together but he hasn't. I get it.
But...I liked Peggy moving on, living her life, getting over Steve, falling in love and marrying someone else. Loss as not-the-end-of-the-world. Then again, I guess that's what Endgame is about: loss as the literal end-of-the-world.
3. On one hand, I see the fittingness of Nat's death, and the fact that her death and Gamora's death are permanent. On the other hand, that's two less women in a movie series that didn't have all that many to begin with.
They did the scene with her and Clint at the ledge well, though. One was never quite sure who it was going to be until they fell over.
4. Always and ever: needs moar Maria. (Oh, come on, that didn't surprise anyone reading this, really.)
The good parts? All the call backs. Pepper in the Iron Man suit. Tony getting to deal with his father before they had a history. Hail Hydra. Thor and the beer gut. Nebula. Carol blasting through Thanos' ship. The women have Carol's back. Sam getting the shield.
Definitely Sam getting the shield.
In short: it's a fitting end to the movie series. All the things you'd expect and well done.
I mean, I liked my version better. But that's also not a surprise. :)
And now I'm going to go pet my cats and listen to some music very loud so I hopefully don't have the Avengers theme in my head when I go to bed tonight...
