It probably helps to compare this film more to 'Twelfth Night' than to 'Cinderella', though it owes both.
I enjoyed it; but then I enjoy anything with Portia Doubleday. She is not as slapstick-funny as Amanda Bynes; but she is prettier; and she carries off the awkwardness of the Kate character amusingly and even credibly. You are inclined to like her character here - she is honest, well-meaning, and determined without being either overly sappy or shallow.
If there are shallow acting performances, they're down to everyone else - Daniel's character was insufficiently developed, making him appear like a caricature of Prince Charming rather than a real-life, modern-day Orsino; and Elise's character is hardly any Olivia. The actors are good enough but they aren't given much to work with.
Being a vehicle for Miss Doubleday is the movie's one saving grace. I really missed seeing her (little spoiler here) on the runway at the end; as it'd have been a major PR success for the company to have had Kate present in her new capacity; and of course she's lacking nothing to have made a good model... if only on her own terms :)
