Comic book movies pretty much exist so that you have to literally disconnect yourself from scene to scene. A person is given an amazing power or discovers one. Thanos obtains the reality gem and can alter reality, for instance. He demonstrates this power by completely faking a scene and then turning Mantis and Drax into goo. But then he never uses that power again despite its enormous advantage. The fights from then on only become dramatic if you forget that he has this power. You have to forget that Strange can cut people apart with portals (extremely handy when trying to get a glove off someone) or stick people in infinite time loops. "We don't trade lives," Captain America boldly states only a few minutes before they make a plan to trade many Wakandan lives for the sake of Vision. Even movie to movie in this interconnected universe, you have to forget things, such as how Thor's true power did not come from an instrument but from himself.
Therefore to me the plot holes are all about the disconnect. Characters don't do things based on motivations or logic, they do things because it looks cool.
