The thing is that the most interesting and novel invention of the MCU is a universe where billions of people turned into dust and then were physically reconstituted on the spot five years later, in a world that had just barely adapted to their absence.
That is wild. That is intense! That is a series of pathos-ridden emotionally complex doorstoppers waiting to happen. Half the entire world! All dead! And somehow we coped with that! And now we have to cope with them all being back?
A whole street of empty houses--surely not everyone there became ash. Some of them moved to better places, now opened by the mass mortality. Some of them died afterward. Who will live there now? Even if inheritances are reversed by resurrection, surely leases aren't renewed. What the fuck happens to everyone who remarried?
What happens to the children snapped back to a world where their parents didn't survive, or the reverse?
But they had to then hastily smooth over this utterly batshit sci-fi premise and get the world mostly back to normal working order as rapidly as possible, without too much emphasis on how literally every person in existence has been placed in a mason jar by a narcissist and shaken twice in five years.
So they could get on with more superhero whack-blam business, which is customarily done against a background of Normality.
This is, tragically, the most Comics thing these movies have ever done.
It is beyond satire that they did this immediately before and during a worldwide pandemic that everyone was pressured to smooth over and 'return to normal' about within 2 years if not sooner.
