I will rate it: 4.5 / 10
All throughout the movie, I felt anxiety and this serious cringe all over me. Why? Its because the whole time, Brie's Veers to Carol take is not likeable. She is trying so hard to be witty and charming. In a word - obnoxious (unlike Tony Stark or Thor).
Also about the heroism part, she DID NOT earned it. The *noble warrior hero* part was awful. Compared to Tony or Steve, the former redeemed himself by stopping all his arms company while doing various research to support the planet. While the latter, even w/o the serum, he is already noble and a hero (the dud granade scene).
Wonder Woman did it better too! She was naive and baddass at the same time without shoving to your face that she is a woman, warrior, noble, hero.
Also, ALL MCU characters HAVE vulnerabilities - while CM has none of it! She is too gaddamn perfect! And that leads to a more problematic MCU PROBLEM:
In the film she is TOO overpowered, and that removes the feeling of dread. The next fights in (Endgame) will be too boring to watch. And if Carol deals the blow to end Thanos, it will be a death scene. Oh yes...
the death of MCU.
PS. The eye of Fury scene is lazy writing. Also, there is no emotional arc because there is only bad acting.
Good things in this film: Samuel L. Jackson and Goose.
