It’s the rare movie that knows its limitations, but also understands how to use form to best convey its strengths, pulling together countless complicated dance scenes in which the relationships between teams and characters come through more clearly than they could through dialogue.

It’s preposterous, but I dare you not to smile at the high-kicking silliness on offer, or the sweetly old-fashioned undertones: as the inevitable final showdown looms, loyalty, hard work and fair play are just as important to the dancers as strutting their stuff.

With even less plot than in previous installments to get in the way of its inventive 3D dance scenes, this fifth pic delivers on spectacle... but lacks in chemistry.

Step Up All In, directed by the dancer and choreographer Trish Sie, signals a slight retreat from the bonkers, protest-themed “Step Up Revolution."

Even if the big numbers in Step Up All In don't always hit the heights of its immediate predecessors, there are enough exultant moments – during the crew battles or Sean and Andie's pas de deux on a carnival ride — to tide you over until the inevitable Part Six.
