When I watched this performance I was actually gobsmacked!!! I thought it was Amazing!!! Yes the vocals aint perfect but its imposible to sing and dance and not be out of breath!!! And the dancing was just enough. The dancing goes with the song, you don't need a lot the lil things make more of an impact (a big dance routine would spoil the song) like the lil moves with the heavy breathing just made me get goose bumps! ...I wasn't a massive fan of Ushers before but I defo am now I think Scream is the best song of 2012. Its a Speacial Song AMAZING!!!
