I didnt mention Gadot but atleast she has some charisma and charming in her interpretation. Brie seems a nice girl but she is not that charismatic.
I personally didn't find her bland I think she came of more stoic and that's a story purpose, because in brie Larson interview she spoke about her character carol having an unemotional side to her. Here's the quote “You have this Kree part of her that’s unemotional, that is an amazing fighter and competitive. Then there’s this human part of her that is flawed but is also the thing that she ends up leading by. It’s the thing that gets her in trouble, but it’s also the thing that makes her great. And those two sides warring against each other is what makes her her.” From that quote I think that's why for the most part she was like that in the trailer, because if you compare human carol to kree carol in the trailer there’s a differences here’s a photo comparison, we will probably see her fun, loving, human side as her character story progresses in the movie.
