Lol @ how Captain Marvel is literally in 6 minutes of the movie and ultimately could have not been in it at all and nothing would have changed. She has one scene at the start where she says one or two lines, then she appears in a hologram scene shortly after and says one or two lines, then disappears entirely for 2 1/2 hours. She's not mentioned by any of the characters and they're just as surprised as the audience to remember she even exists when she pops up at the end to make a big entrance and look like a bad ass then get power punched off screen like a cartoon character. Absolutely nothing from her movie or storyline was brought up beyond a passing "yeah, where were you all this time" line. Her addition to the MCU as this super over powered being and being the last thing before End Game like she was ultra important now seems like a troll job. She easily could have just popped up in THIS movie for the first time with no back story and it would have been exactly the same.
Cap picking up Mjölnir

Cap finally saying Avengers Assemble

The girl power brigade

Pleasantly surprised to see Rhodey in so much of the movie. He's been such a minor side character in the ensemble movies, yet he was an integral part of the team in this one.
The first act was really interesting because there was zero action, just the somber reality of a world where 50% of the population got turned to dust and how the remainder is dealing with it. Then it ends with lopping off Thanos' head in the first 20 minutes

This movie went so comic booky idk how they can continue the series after this. We're doing time traveling/dimension hopping different characters from different timelines in the wrong time, the epic battle with every character ever. Going forward I have to imagine the solo movies will go smaller and more personal again for a while because it certainly can't get bigger. I got a real

at them bringing back almost everyone from every movie, even Natalie Portman, but still wouldn't bring back Coulson to the main crew
It certainly feels like there was a very clear dividing line between before End Game and after End Game. The original team: Tony is dead, Hawkeye went home to be a family man, Hulk is disabled, Cap and Thor passed on their positions (and wtf at Cap giving Falcon his shield when Bucky was RIGHT THERE, he'd known Falcon dude for like 3 years before the snap

) and Thor joined a different team that will be around in space. Thanos is dead in multiple timelines, the Infinity Stones storyline is wrapped up, Cap got his happy moment, Tony got to do a big wrap up of the past decade and all the surviving characters said goodbye. It's a pretty definitive end for a series that still has 15 movies announced. It's a good jumping off point for a lot of people, I think.
Going forward idk about the MCU: The New Avengers: Spiderman, Black Panther, The Falcon as Captain America, Ant Man, Scarlet Witch, Captain Marvel, War Machine, Dr. Strange, Valkyrie as the Queen of Asgard but idk if that means she's filling Thor's role. Thor as part of GOTG. I guess what was telling was that all of the snapped characters were absent for 90% of the movie and I didn't miss them at all. It was rad when they all came back and stuff, but I don't really have much connection to any of them (Hated Homecoming, Falcon has been lame in every appearance, no interest in CM, BP was cool, didn't like Dr. Strange) and am not particularly interested in their stories after this movie. But much like Star Wars, no one is ever really gone, as multiple of the "really dead" characters had already announced movies/series anyway. I'm sure there will be appearances from Tony/Cap in a Disney+ series, especially now that alternate/branching timelines are established in continuity.
Chris Hemsworth must have been so happy to not have to do any extra work in the gym this time around. Every other appearance as Thor he's gone on a crash course and had to put on like 50 pounds before losing it for his next role, this time he could just be his normal self and wear a fat suit. That's also a really...interesting way of handicapping him in the end battle

Really the whole series is irrevocably broken now that they can time travel whenever they want. Hank Pym is alive so he can make Pym particles for years, and then the rest of the team can make it, and if they run low they can just go back to the past and get some more. This type of shit is where the weight of decades of comic book bullshit comes crashing down and leading to reboots in actual comics, so I wonder how long it will take them to reuse this shit or find some reason why they can never do it again or just flat out "this is a different timeline we're in now things are different lolz". This is like the "why don't they call in the other Avengers" but amplified by 300. By the end of the movie they were using their
THIRD time machine.
Tony dying didn't really get me, but some of the relationship stuff throughout the movie did. The first half before they got into action mode was so interesting, I was wanting like whole movies out of various side plots in the movie just about various characters/relationships dealing with the loss and grief of the snap. I thought it would have been amazing had Thanos' bombardment actually killed the whole team at Avengers HQ after they undid the snap.
Idk what the next big universe level threat would be (Kang? Some Dr. Strange bullshit?) but I'm not really interested in what comes next. This felt like the wrap up and anything after is EU shit you can skip.
