Captain Marvel was boring and bland, and Brie has the charisma of a potato.
But the biggest reason the movie was shit was the character's arc and the central message. "When men try to get you to control your emotions, they're making you weaker. Let your emotions flare up out of control and you'll be all powerful!"
I know, I know, silly comic book movie, but these things have themes rooted in the actual human experience. This movie explored the eternal difference between men and women and came to the most retarded conclusion possible.
