@the way I see it -

NO, not "hating".... more like waiting with bated-breath and being severely disappointed! This was the 'ONE-TIME' when, the "stage was set," for Rihanna to show the world, and silence her critics, regarding her dancing skills - or "lack-there-of!"

So NOW, there can be NO DOUBT: put in "her-element/natural-setting" and given "FAIR CHANCE" for her to "prove herself" - Rihanna can't dance!
.... Members of the jury, the evidence proved OVERWHELMING - you've ruled - the court of public opinion thanks you, and the "State-of-Popular-Culture" thanks you - you're NOW dismissed!
