Wow! What an amazing movie. Seriously my new favorite in the series. I couldn't believe the amount of throwbacks and cameos they had stuffed in there.
To keep things simple I am going to do a few random musings then go over the big thing, time travel.
Was so happy to see Mjolnir back! Even if only temporarily. It makes sense to me why they made Thor get so out of shape. He would have been a beast dual wielding his weapons if he was still in prime shape. The scenes with the parents and their kids kept murdering me. Clint losing his family, Cassie finally being able to see Scott again, Tony just trying to be a good dad, Morgan losing her dad, oh man my heart.
I can't believe they "Harry Kim'ed" Gamora, I was not expecting that. Speaking of that whole thing, how the fuck did Thanos fit his whole ship through the time machine considering it was supposed to use Pyrm Particles to shrink to quantum sizes? Did they steal Nebulas and figure out how to use it? I guess I missed that part?
Actually why where the Avengers even using ships? Thor supposedly has the power of the Bifrost now. Actually, wait, in Infinity War while they were on that circlular ship, Dr. Strange tells Tony to turn it around back to Earth, but he does not know how so they decide just to go to Titan. Now we know Dr. Strange can just sling ring across the universe. Why didn't you just do that!? Haha.
I was honestly surprised to see The Ravagers at the fight. Once I saw the Wakandans I quickly expected the Sorcerers and even the Asgardians since they now live on Earth, but the Ravagers felt out of the left field. (They even had Howard the Duck with them!) Seriously the amount of cameos was blowing my mind. They had at least one side character from pretty much every movie in some way shape or form.
Also, I don't know if Peter Parker has the best luck or the worst. Now that we know all the people came back, but lost five years, it's pretty much official that all of Peter's friends, including Ned, were dusted. On the one hand that's terrible, on the other though it's the only reason he is still on the same level as them. Could you imagine Peter coming back and finding out all his friends graduated years ago?
Speaking of the dusted, it pretty much confirmed that all the dusted people returned directly to the point they vanished, as Doctor Strange and the others were on Titan when they used to sling ring. This is going to be one hell of a bad day for anyone that was traveling on an airplane. At least they won't have long to contemplate what just happened.
Time travel in this movie was played very loose, but honestly I am curious. The Ancient One made it out that time was one long flowing line, and that by removing a stone it would make a "doomed timeline". Banner explained that putting the stone back right at the point it left would fix that, but they changed other drastic things in that timeline, like Loki escaping. Did those still twist off into other time threads? Or much like The Ancient Ones visualized time stream, would putting the stones back actually "rectify" the main timeline even with small changes?
Example, we saw at the end of the movie Steve stayed in the past to be with Peggy, but that event totally destroys her known history. You could say that they just agreed to keep it on the down low, and not involve themselves, but remember during Winter Soldier, Peggy was revealed to have Alzhimers. She wouldn't be able to keep up the ruse in front of the younger Steve once he was unfrozen if her memory was failing as bad as they showed. If it sort of finds ways of correcting itself, then it could be even with his changes, time turned out the same. Might explain why none of them noticed the old dude sitting like 30 feet away by a lake. He may have just materialized from the correction.
My best theory is that when the time stream changes in little ways, some of those changes "slip through the cracks". For instance, we know Loki is getting a series on Disney+, and we saw him escape with the Tesseract in one of the time hiests. It could be this event caused an alternate Loki to slip into our universe much like Gamora did.
Anyways, just my own musings. Great movie.
