I haven't seen it, but I'm going to guess from what I've seen in trailers that she's not Ernie Hudson. I didn't get a down-to-earth vibe from her like Hudson's portrayal of Winston, and it seems more like she's a the sassy black woman stereotype. Loud, overly-assertive, etc.
In general I don't think any one actor is being singled out (though I haven't been paying too much attention to a thing I have no interest in ever seeing), but that everyone is pretty much caught up in the patchwork quilt of fan hatred. :\
