Agreed, and the Russo brothers trying to explain it after the fact only proves they (and the other screenwriters) failed to explain something no one can realistically understand in the first place. Having Hulk mock other movie time travel ideas was just to avoid that which the Russos ended up having to do since the film's release: attempt to counter criticisms from audiences who have their own ideas on how time travel works.



More convoluted screenwriting. The snap was only stated to bring people back, but the physical world was still 5 year later and those areas abandoned / in a state of disrepair should remain that way at the moment the snap happened, including Hawkeye's home, even as his wife and children reappeared.



This is one of the numerous problems with the movie; the Soul Stone demands the seeker to sacrifice something they love in order to obtain it; Black Widow committing suicide did not represent that, as Hawkeye--being the one left to obtain the stone--did not get it because he sacrificed Black Widow, as seen with Thanos & Gamora, so the film simply used plot convenience for an empty stab at drama contradicting its own rules. Psychologically, Black Widow always intended to commit suicide (once learning how the stone is accessed), so even as Hawkeye was losing his grip on her hand, that was not an act the Soul Stone (or its rules) would perceive as he--the seeker--sacrificing anything.




I'm guessing more plot convenience to explain the Loki TV show.



Well, that would not make sense if that's what the movie implied, since the serum will work the same (slowing the aging process) no matter what the user does (or does not do) with his life.



That's due to movie being bloated in an attempt to be "epic" and tie up the fates of characters tied to actors with expired contracts.

For all of the build up of Sam as Steve's new best friend, you are correct in noting how little development the relationship received (post Civil War). And before someone says that was not the focus of the movies, we had more of the Wanda/Vison relationship in Infinity War, and neither were as established as basic characters as Steve and Sam. Some will argue that the Vision/Wanda relationship was key to the Infinity War plot, but its outcome (Thanos obtaining the Mind stone) was going to happen whether Wanda's interaction happened or not, as we see when he reverses time to get it.

On an emotional standpoint, there's not much there as the Vision/Wanda "romance" seemed forced and lacked the years of development the comic book counterparts had to make it even remotely believable, thus the Endgame scene of Wanda screaming (at Thanos) about his taking "everything" away from her rang hollow.




Plot convivence again. Make some grand, threatening statement about a McGuffin, but never have it live up to the hype. The consequences of destroying the stones is never see or fel--not even in a throwaway shot of some other planet. Its just "the threat of" and nothing more.



Same here. But, we live in a time where the visual and idea of a strong Thor was considered "boring" to some, when that original personality was a necessary contrast to the other Avengers and Loki. Turning him into a fat alcoholic made his presence a joke, and for all of the stated importance of the stones plot--having fat Thor as alleged comic relief was distracting. So, now he inexplicably gives up being the ruler of his relocated people to become a comedy sidekick. I cannot recall another 21st century superhero movie or series that downgraded and destroyed a character to this degree.

This was anything other than a satisfying ending for the original characters. A lot of noise and "this is important!" dialogue, but it never felt that way.
