In the past, the MCU has tried to claim that it’s all about family, particularly with the Avengers. In Endgame especially, there was a focus on how these characters supposedly see each other as family, because a lot of them are estranged from their own biological family (or their real family is dead). However, this always falls flat because the audience is never really shown why the Avengers are a family, they’re just told about it. The moments that are actually seen on screen are just of the Avengers constantly fighting, to the point where they have the relationship of coworkers, but nothing more than that.
