While Mean Girls proved there's life left in the teen comedy and Shrek in the contemporary fairy tale, this proves just how carelessly a hybrid can be slung out and still, somehow, please a portion of its adolescent audience.
Sam (Hilary Duff) slaves for her wicked stepmother (and minging step-siblings, natch, what with this being an update of the Cinderella myth. Clue's in the title, folks) while dreaming of her anonymous cyber soulmate. At a fancy dress party rendezvous, he's revealed to be school hunk Austin (Chad Michael Murray) - swoon! - but he doesn't recognise the eye-masked beauty as lowly diner worker Sam. What will happen if he finds out? Will he use the mobile phone (read: glass slipper) she left behind to track her down? No, that would be too easy. So would making humorous use of the 'ugly' sisters.
This is simple, lazy storytelling rendered merely functional by appealing leads and the eternal lure of romantic fantasy.
