We’ve had ‘Streetdance’ (twice). Now meet ‘All Stars’, the UK’s latest attempt to ape America’s lucrative tween dance scene (in 3D). Ethan (Theo Stevenson) is a cheeky schoolkid who throws a talent contest to save the local youth club. His own dance crew is an unlikely mix of posh kids and overeaters, trained by Jaden (Akai Osei-Mansfield). The young performances are variable, but the saving grace is the grown-up cast, including Ashley Jensen and Mark Heap, who don’t hold back while delivering the cynical one-liners. TV director Ben Gregor brings inventive visual touches to his dream sequences – overambitious, maybe, but welcome in a genre that’s become formulaic to say the least. Yes, there are clichés: the warring dance tribes, the blending of dance genres as if no one’s ever thought of it before. But ‘All Stars’ is funny and enthusiastic enough to entertain kids, if not their elder siblings, who may not buy this scrubbed-up version of teenaged Britain.
