She could be if the director had directed her to actually emote instead of just talking at a stonefaced Carol about how she's too emotional the entire time.
This isn't world series poker, goddamnit!
Small tells of an emotional reaction aren't enough for the audience when you have explosions and fighting going on all the time.
You need to at least have her slip up noticably once or twice to establish the Kree equivalent of poor impulse control.
She already shoots things for no reason, so we could have had her reprimanded for such angry behaviour right in the beginning instead of making lame jokes about her pointless aggression against 90s references.
It would be a natural outlet for stress in a restrictive society she doesn’t belong into.
If you establish that.
