Larson seemed to care more about her message of hate towards men way more than attempting to put any actual effort in associating emotions with her character. Main fight scene ruined by the stupidity of choosing "Just A Girl," when she's not just a girl at all, but an overpowered alien from another planet. So, technically, she's not even giving a message of empowerment of women, since unlike Black Widow, she's not actually a WOMAN.
Personally, a 2/5 because let's face it. In Alita: Battle Angel, Alita actually has more emotions, and she's a Cyborg.
