This is a horrible video.  It's her dancing in her underwear looking like a man wearing a wig.
It's basically Gimme More part 2 without the pole.  The song is just average and the video killed it.  Worst video of the year.  Maybe decade.  
I bet Lady Gaga could sit in a chair and move her arms a bit and you guys would go crazy, "OMG Lady GAGA danced!!!!"
Britney Spears danced soooo much better in Hold It Against Me.  It was just poorly executed/edited but overall Britney's dancing beats this.  Britney > Lady Gaga (Video/Song/Dancing) wise.
