I was thinking about how the Marvel Cinematic Universe has the Hydra was part of Shield, revealed in Winter Soldier
For me, this was a cool twist. It also fixed one of the problems of the previous movies. For example, in The Avengers, why did Shield not want the Avengers team put together. And even when they did, why did they go for nuking New York.
I mean, it still made a couple of problems. But thinking about how there first (not last) resort was to nuke all their heroes as soon as they were together foreshadows that maybe they aren’t that good.
