She plays way more of a role than Bobo Fett ever did

I mean, Fett was always popular because he looked cool more than because he contributed a lot, but he does track down the Falcon via his own initiative, leading to the capture of four of six main characters.

Captain Phasma's contributions so far consist of getting captured in Force Awakens and thrown into a garbage compactor, briefly capturing Finn and Rose because a droid spotted them, then getting her ass kicked by Finn in a fight and falling into a fire and apparently dying. And let me tell you, as someone who really likes space marines in sci fi in general, the idea of a kickass stormtrooper commander as a central antagonist was real exciting to me going in. Phasma is wasted.
