My friend disputed this saying she pretty much played the same character, i.e. an incarnation of a point on the slut spectrum.

I'd argue this is what happens whenever SNL has a female guest on who's public image is that of 'sex symbol', which is the skits turn into the juvenile wish-fulfillment fantasies of the writers. I still shudder when I think of the time Sharon Stone hosted. So not really MF's fault but more the failure of a lack of imagination by the writers. Because they've been doing this shit for *years*.
