Isn't that what I said? That it's an impossible task to show every day of their lives? It didn't seem to me that any character at all was in a different place in their lives. They were all right where we left them on their own individual paths from the previous movies. Cap & Tony still aren't talking. Cap is still a do gooder, Stark is still an egotistical narcissistic *** that won't admit what he did in CW was wrong and Cap was right. Widow & Falcon are still following Cap. The Government still considers Cap & his pals fugitives and criminals. Rhodey is still General Ross lackey as he is a military man, whether he agrees or not. Bucky was awoken only after his request that he was "healed" as seen at the end of BP. Drax still wants to kill Thanos. Quill & Gamorra are still doing their relationship dance. Groot is now a teenager. Rocket is still Rocket. Nebula wants to kill Thanos. Peter is still an inexperienced kid in high school trying to figure things out. Vision & Wanda are still trying to figure out their feelings for each other & how/if it can work. Strange & Wong are still the protectors of our dimension. It's all there. what your asking for would mean another Iron Man movie, Cap movie, Spider-Man movie, Strange movie, GOTG movie, a Scarlet Witch & Vision movie, Black Panther movie with Bucky, all ending on the same day that IW starts. Thor Ragnarok is the closest movie that feels like a direct lead in, cause it was. There may be some holes here and there, but nothing of significance to me. I didn't need to see Tony & Pepper's romance blossoming to the point of marriage and having a baby.
Yes because there was a fraction of the characters that are in IW. And your listing group moments, not individual moments. Meanwhile at the same time people complain that the villain Ultron (like most Marvel movie Villains up until IW with Thanos) wasn't developed enough at the expense of the heroes characterizations. IW is Thanos' movie. He was the star.
But its not. There were 8 - 10 hours of episodes over a few days leading to that, just like 17 movies leading to this. And you can't do that in movies. Some time needs to pass. Again, that's what I said. Ignoring every episode of the season and just watching the 2 part finale. IW is the 2 part finale of 10 years of storytelling, but we haven't seen part 2 yet. The next Phase 4 will be and feel completely different as said by Feige.
