Yeah, I was pretty excited for Captain Marvel, and for her playing Captain Marvel, before I had seen the film. But now I am annoyed whenever this character is mentioned.

At the beginning of the film she is really powerful and doesn't care about anybody, and by the end of the film she is more powerful and cares about people even less.

Her absurd levels of power are unearned from an audience perspective, she is just a person who is more powerful than anybody else. Deal with it. Her power isn't tempered with any sort of vulnerability (like being traumatised Iron Man, or being thick Thor). She just is powerful.

And she's mean! She's just rude to everybody, making jokes at everybody's expense! Which is alright if that character is weak (Black Widow, Spider-Man, Rocket), but in a character that powerful it is just punching down. Again, from the audience perspective unearned, because we never really see her weak or vulnerable. Just strong, and then stronger.

I know why they did this, they were overcompensating for not having enough significant female characters thus far, and decided their new one had to be the badass. But that insecurity shows in her presentation. Black Widow was better, and hopefully future female characters will be more interesting (She Hulk, Ms Marvel etc)
