She's just really boring and one-dimensional because they're too focused on making her ICONIC and YAS KWEEN to give her a real personality. She was never a great character before, but at least she felt like a character and not a plot device. The worst part is that she has plenty of potential to be the character they want her to be and to assume the role as Marvel's Wonder Woman if they'd just stop trying to market to feminists who want female characters to be little more than quotable/screencappable validation machines and hired someone who doesn't care about social media politics to give her an actual personality and a run that fits in the superhero genre. Ideally, Nu-Carol would basically be the Hal Jordan of Marvel, an arrogant and headstrong jarhead who makes up for an abrasive personality with huge brass balls and a genuine heroic spirit. Stop focusing on how iconic and meaningful she is and start actually making stories which elevate her to that status.
