Pretty and pink it may be, but the high-energy, frothy feel-good Legally Blonde, running at Wales Millennium Centre until August 25, has a serious, if obvious, point to make.

Elle Woods is blonde, addicted to pink ... and to her boyfriend Warner Huntington, who unceremoniously dumps her for her lack of seriousness as he heads off to Harvard Law School. But Elle wants him back and it turns out that he won’t be the only one to learn that judging a girl by the colour of her hair and her wardrobe isn’t entirely reliable.

Legally Blonde The Musical turns up the camp factor to the max, with Lewis Griffiths getting arguably the most enthusiastic reaction for his memorable turn as Kyle, a masterclass in archness.

Faye Brooks as Elle attacks the pinkness with passion, yet handles the transformation into a girl to be taken seriously with total conviction, and Rhona McGregor stood in for Jennifer Ellison (who joins the show on August 24) to deliver a beautifully judged, touching and brilliantly sung performance as Paulette.

While it carries you along on a wave of support for Elle, there are things about Legally Blonde the Musical that disappoint - the opening number had megawatt energy, but singing that verged on the shrill made it all but incomprehensible, and Gareth Gates playing Warner Hartington the Third had far too little opportunity to show off a great voice.

True, there’s a moral to the story, a nut in the heart of the strawberry cream, but this isn’t a musical to make you think too hard - and you’re probably more likely to remember the sugar-rush of a feel-good show than you are to find yourself humming a score that has few stand-out numbers - the skipping number looked extraordinary, but sadly I can’t remember the song.
