I feel like if the MCU were smarter, they would have some media showcasing what happened between Avengers Infinity War and Endgame.
How would have world wide governments dealt with the mass panic and societal instability that would have come along with the snap, how would the individual Avengers have dealt with the emotional impact of losing for the first time and feeling they have failed in their responsibility.
One of the weirdest things in Endgame, is how most of the Avengers (save for Thor and Clint) actually seemed relatively stable post Infinity War. Steve is kinda down but he has his own support group and doesn't seem anymore sad than he was when he was displaced from his own time, Tony has a new family living in a cozy house, Black Widow is the same Natasha is the same Natasha as before, and Bruce is actually doing really well shown by the fact that he managed to fuse his Hulk and Bruce persona together and is no longer struggling with dual identities and feeling he has something in himself that he wants to get rid off.
