It's great! It's sexy, it's stylish, it's pretty much everything I want a Britney video in the year 2011 to be.
I can sit here and nitpick about little things, like the fact that for a song that demands we "keep on dancing till the world ends" the video is a little bit light on the choreography, or the (once again) chaotic editing (Did they give us enough shots of the extras writhing in ecstasy and making orgasm faces?), but it was still really well executed and seems like a step in the right direction... not that I think HIAM is the horrible misstep most people make it out to be.
And of course, there will be that "dance version" which will feature more of the choreography (seems like a mistake to leave it out in the first place, but whatever) so I'm sure I'll be ridiculously pleased with that version.
