Talking to comic book nerds many agreed that Captain Marvel was just a dull character
What comic book nerds were you talking to?
Carol Danvers is a very rich character in the comics. With a host of experiences that make her extremely layered and interesting.
She was a natural choice for a movie adaptation. The problem was, none of this rich character history was mined for the movie at all. She was written as one dimensional, thus giving Larson nothing to work with.
I'm not a fan of Larson's politics either, but she is a good actress, and she was an excellent fit for the Carol Danvers of the comics. Able to portray a strong female character that is also damaged. Unfortunately, that Carol Danvers never made it to the screen.
Now as this was an origin story, heavily changed to fit inside the MCU, and most of Carol's trials in life come after her origin, there may still be a chance that the movie version of this character can be saved.
But to write off the comic book character as boring, is just plain wrong.
