She has absolutely no charisma especially for a character who's supposed to be a leader . Bad casting IMO.
About 90% of her dialogue in that the trailer is her implanted kree warrior personality which I imagine she'll gradually lose over the course of the film. I do worry that Brie has oversold that part of it. The comic book character is so inconsistently written I'm not sure you could really say she's supposed to be a leader.
