Wesley Case of '' The Baltimore Sun '' stated that video " is typical 2011 party-starter — sweaty bodies , futuristic DJ-gear , well-timed faulty sprinkler system — but it captures the track 's raging mood perfectly . " Gina Serpe of E! Online also compared the video to " I 'm a Slave 4 U " , saying , " There 's nothing wrong with a little nod to vintage Britney . Plus , sweaty dancers in underground tunnels pulsing and writhing in sync to the music ? Seems like as good a way as any to survive the apocalypse . " Willa Paskin of '' New York '' commented that Spears " tries hard not to make the same mistakes as the inadvertently depressing ' Hold It Against Me . ' There 's more dancing — though it 's still largely arm-related — and much , much more smiling . " The music video was nominated at the 2011 MuchMusic Video Awards in the category of International Video of the Year — Artist , but lost to Lady Gaga 's " Judas " . It also received two nominations at the 2011 MTV Video Music Awards in the categories of Best Pop Video and Best Choreography . Spears told MTV News she was " completely flattered " by the nominations . She lost Best Choreography to Beyoncé 's " Run the World ( Girls ) " , but won Best Pop Video
