Went to a 9:30 screening last night. Roughly chronological thoughts...
Opening with Clint's family was both an effective way to bring us right back to the somber mood from the end of Infinity War and establishes why he's doing what he's doing when Nat catches up with him later on.
Killing Thanos 10 minutes in was a great curveball, and Thor's "I aimed for the head" was a great line.
The revelation that it was five years later (versus five days/weeks/months I guess) drew audible gasps from the audience.
As SleeperAwake said, there were some nice character moments in the initial scenes five years in the future.
I really enjoyed the time heist portion of the film. Some fun character pairings and revisiting of the old movies.
Cap versus Cap fight ftw.
Not sure what Loki swiping the Tesseract means for whether he can/will show up down the line in the MCU.
The only exception obviously was Clint and Nat retrieving the Soul Stone. Stomach sank as soon as I realized that those two were the ones off to Vormir. Figured it was going to be Nat who was the sacrifice because they wouldn't open with Clint losing his family and not have him get them back.
Did not expect to get a Stan Lee cameo, so really enjoyed when he popped up in New Jersey
Once they got all the stones together I was thinking how, as much as I was enjoying the movie, I was expecting something more epic. Then Thanos showed up, and he brought all the epic with him.
I don't think I have words to describe the totality of how awesomely epic the final battle as a whole was.
There were a number of cheers throughout the battle, starting with when the first of the teleportation circles that Wong and Strange opened up appeared.
Easily the biggest roar of the night, an atmosphere I've never experienced in a movie theater before, went to Cap wielding the hammer. People were losing their damn minds.
In their defense, f$%@ing Cap wielded the f$%@ing hammer!!!
The "girl power" moment didn't bother me, because there were team-ups happening all over the place
Absolutely awesome way for Tony to go out, "and I. Am. Iron Man." and then the snap.
It's amazing how quickly the theater went from feeling like a raucous party to being somber and silent enough that, if not for all the quiet sobbing, you could hear a pin drop.
I wasn't great, but I was OK at first. No tears, but a couple quiet ugly dry sobs. Then they cut to the "Proof that Tony Stark has a heart" memento and it was game over for me.
My interpretation of Cap's time travel adventure was that after returning the last of the stones instead of making his last jump back to the present (meaning post Tony's funeral) he made the jump back to the 1940s to make his date with Peggy and stayed there. Then old man Cap showed up at the right place at the right time.
I'm surprised Bucky wasn't given the mantle of the shield, but I'm not mad that Sam got it either.
Please please please give us an Asgardians of the Galaxy movie. I don't know if they'll do it because it almost feels like a demotion for Thor in some ways, but I think it would be a blast. Plus, with Asgard gone it feels like it'll be tough to give him another solo film in the future.
Overall I'm in awe of what the Russos managed to pull off between Infinity War and Endgame. The sheer scope of what they were attempting and the expectations attached to it were enormous, and I don't know that they could have done any better. While the MCU will obviously continue on, this felt like a unique pop culture experience that will be tough to ever duplicate. Essentially a conclusion to a 22 movie story arc that captivated the world. I've got a ticket to see it again tomorrow night, because not only do I want to see it again, I want to see it again with that opening weekend audience where people will be cheering along and just losing themselves in the universe that Marvel's created. There are certainly better movies that I have seen and will see in the future in terms of overall tightness of plot and capital A acting and such. But as an experience this is unrivaled.
