After Avengers: Endgame, it was only a matter of time before the Accords were repealed, though Agent Woo (Randall Park) at least referenced them when arresting Director Hayward (Josh Stamberg) in WandaVision. The whole thing was handwaved away in an episode of She-Hulk: Attorney at Law, as Matt Murdock noted that the Sokovia Accords were no longer a factor. There are a lot of reasons for the Accords to be done away with, but taking the big conflict from one of the most important MCU movies and just shrugging it off felt wrong.
All Out of Kang
After Thanos was such a hit, the second trilogy of Marvel phases needed a big villain to fill the void. Jonathan Majors’ He Who Remains debuted in Loki, promising a multiversal threat and the horrors of countless variants of Kang the Conqueror. Around the release of his antagonistic appearance in Ant-Man and the Wasp: Quantumania – which left a lot to be desired – Majors was wrapped up in a scandal and trial that put the character’s future in question.
In the end, it was decided to scrap plans for Kang, replacing Avengers: The Kang Dynasty with Avengers: Doomsday. While the Council of Kangs may possibly play a minor role in Doomsday in some fashion, as it is right now, the mad scientist fraternity is a loose end being plucked out of existence by the TVA they ultimately created. A letdown if there ever was one, it also put a damper on one of Quantumania’s high points, where a confused Scott Lang did his best to shake the fear that his heroics in stopping his specific Kang somehow made things worse for all of reality.
The Anti-Skrull Agenda
This one isn’t so much the result of a bad creative follow-up, as it is the result of bad communication and lack of creative synergy. Secret Invasion finished up with a rather dark ending, where President Ritson went full-on bloodthirsty when it came to races of aliens living among humans. His anger stoked the fires of the public’s distrust in government officials being human beings and the whole thing was turning into a mess. In a different time, in more competent hands, this would have been a dramatic new status quo for the MCU. Being that it was Secret Invasion, considered by many to be the worst MCU project, the events of this show were all but ignored by everything that followed.
This was especially awkward when The Marvels was released soon after. Not only did it have a much easier solution to the Skrulls’ displacement problem (just throw them in New Asgard!), but Nick Fury had a very different disposition. As for Ritson’s declaration of war against all off-world aliens, time showed it must have been incredibly unpopular to the public. He was replaced by Thaddeus Ross (now Harrison Ford), showing that the American people would rather vote for the guy who tried to hunt down the Hulk and Captain America than the guy who claims Thor and the Guardians of the Galaxy are enemies of the state.
Monica’s Disdain for Captain Marvel
An interesting moment in WandaVision came when Monica Rambeau, Jimmy Woo, and Darcy Lewis discussed Wanda Maximoff’s power level and success in fighting Thanos. Woo noted that Captain Marvel also held her own in the Endgame finale, to which Monica shut him down, as she did not want to talk about Carol Danvers in any capacity. Once a little girl who looked up to her Aunt Carol, Monica came off as bitter. It set up a unique dynamic for The Marvels, as Captain Marvel would be working alongside a young hero who idolized her and a hero who felt let down by her actions.
