With shtick as dull as it is ill natured, this appallingly dumb and tasteless inversion of the Cinderella story features the voice of Sigourney Weaver as a generically shrieky wicked stepmother who discovers she can tinker with fairy-tale endings, notably that of Cinders (Sarah Michelle Gellar), who sports a short black Audrey Hepburn ‘do and a mistaken crush on a narcissistic prince (Patrick Warburton) brazenly ripped off from Beauty and the Beast‘s Gaston. Remember those fabulously giddy bits in Shrek that riffed on just about every fairy-tale character known to Western man? Well, here, director Paul J. Bolger and screenwriter Rob Moreland have drained the affectionate wit out of the Shrek franchise’s satire, giving us instead a barely sketched-out story line involving an inept fairy godmother, a sulky dishwasher (Freddie Prinze Jr.) headed straight for love interest, two run-of-the-mill critters with little to do but try to seize the attention of the under-5s by force, and quantities of unimaginative CGI. I spent the movie scratching my head over which audience Lionsgate is hoping to tap with this noisy rubbish. YouTubers? Tots with ADD? ELLA TAYLOR
