They need to either write her out (not gonna happen), or totally re-imagine her. She is a terrible actress (in this). In trying to look tough she just looks ridiculous. Compare her to the rest of Star Force. All of them looked like seasoned warriors to a man, and woman, apart from Vers who was trying to act tuff while failing miserably.
Look at the poses she takes up in these scenes. Since was does being tough == clenched fist? Always... It is beyond a joke. Other actors show their steeliness by posture, stature, facial expression, tone of voice.
And it is not about aiming her weapons - else it would be held out like all the other armaments. See pic 4... It is because it is her free hand.
Lookin' tough
Gemma Chan showed ten times the sass, ten times the charisma, came across like a menacing warrior without any of the hackneyed physical theatrics. She displayed 10 times the personality and likeability with less than one tenth of the number of lines. All in the same film, with the same directors.
