It's equal parts 'Flashdance,' 'Burlesque' and 'Lambada', all parts ludicrous - but we aren't here for the story any more than we watch Bla Tarr for the salsa numbers.

There's too much color and energy and frenzy in this movie to discount it entirely, but it has a disconcerting tendency to undercut its best notions with some singularly awful moves.

With the most wooden leads of the series to date - an MMA fighter and a 'So You Think You Can Dance' alum - the drama between the dancing has never felt more interminable.

'Step Up: You've Seen All This Before' would be more accurate, but Summit Entertainment's marketing department knows that wouldn't help sell tickets.

Delivers plenty of spectacular fancy footwork in what is otherwise a flat-footed fantasy.

While dance purists won't be impressed by the energetic and athletic choreography -- the dancers have clearly learned routines but not necessarily technique -- date-movie audiences will likely want to go out dancing afterward themselves, and that's fun.

The choreography is solid throughout, but director Scott Speer gets in his own way every time, relentlessly shifting camera angles to close-ups and reaction shots when he should be letting us witness the spectacle.

There isn't a franchise around that matches the kids' moves in the Step Up series. We just need a better reason to dance along.

No one goes to a 'Step Up' movie for the plot or the romance. Only the dancing matters here.

Busby Berkeley would have approved of the hijinks director Scott Speer gets up to with his 3D cameras

Though the location-specific choreography looks like it could be impressive, the film's frantic cutting style makes it difficult to simply enjoy bodies moving in space.

Contrary to its message, it will not change the world. But the dancing will make you sit up and take notice.

The plot is pure boilerplate, yet the draw of this franchise has always been its fancy footwork, and the movie's stuttering, herky-jerky spectacles of impassioned movement are pretty extraordinary.

Not as cringe-worthy as you would expect from the fourth 'Step Up' installment.

Sadly, somewhere between a split and a fist pump, Revolution fell flat, and I found myself wishing for Magic Mike in 3-D.

Despite their infectious energy and some mind-blowing moves, there's a chaotic formlessness to even the best of these set pieces

[Guzman and McCormick] zero acting experience - and it shows. Same goes for the first-time movie director, Scott Speer, who can't coax even a passable performance from his amateurish cast..
