Okay so I don't know why this movie is getting so much around the world but I think that movie was pretty good.
Yes it lacks a proper villain but a origin story is never about having a proper villain its about how a hero finds himself/herself, tries to know their place in the universe and to understand that with great power comes great responsibility 😋.
The movie perfectly covers those points nonetheless.
My only disappointment would be that you should have at least made Stan's appearance more funny and impactful. It is one of those last times we will see Stan making a movie appearance ever 😢.
Although I don't think the makers had anyway of knowing that it was one of those last times.
