As someone who watched all the "original" marvel movies, up to a infinity war I think, I don't think anyone expected any depth from them . I wanted to watch a classical sorry full of non-subverted tropes about a hero fighting an adversary, going through a classical hero journey, and eventually prevailing (possibly sacrificing something in a process). This is a tale as old as time and I don't think there's anything wrong with it.
Of course marvel movies are devoid of any greater meaning and don't really prompt the viewer to think about anything deeper, but for me it's a feature, not a bug - when I want to think I open a technical book or start a side project.
