Where is Captain Marvel?

Rating: 5/10 (2 November 2019)

In her solo-movie, we learn that she has incredible powers and should be the key to an ending to the war.
Then in this movie, she is absent all along and when she shows up, she is suddenly weaker? I couldn't help but recognise that the other male superheroes (who are less powerful than Captain Marvel), as Captain America, get unfairly too much more attention than her.
I would say same about Thor, he is literally a god and then this Captain America appear to be stronger???
It's pretty clear that the producers favour certain characters.
This makes the movie incoherent and a bit nagging.
