When film industry legend John Huston made the durable 1982 adaptation of the Broadway musical Annie, he was accused of making a bit too literal and lumbering an entertainment, but fans should likely accept Huston’s creation or Rob Marshall’s 1999 TV re-do as an authoritative version. Will Gluck’s 2014 remake of Annie (C-) starring Quvenzhané Wallis is a beast of a wild card, a modern-day remix of the former Depression-era tale told to an auto-tuned pop beat with basically the same structure as past incarnations but very little of the faithfulness to legitimate song and dance craft. The model here is strictly in the High School Musical quality zone; and only because of the paucity of films in the musical genre is it worth an analysis. Writer/director Gluck, who made the amusing Easy A, isn’t without talent in terms of comedy and sentimentality, but he throws in too many zany elements from smart-home technology to convoluted subplots and too much flash and half-baked jokes when he should really be tightening a bloated story and giving some of those musical numbers a bit more buoyancy. A few mild gross-out gags and inconsistent characters distract from the moments that do actually spark. As the millionaire who takes in the plucky foster child, Jamie Foxx improves in his performance as the film rolls on, ultimately finding some soul in the role. Ditto for Cameron Diaz, whose acting at first seems from another planet: she too gets better as her boozy Miss Hannigan finds her way through the uneven film’s labyrinth. Wallis is largely charming and even gets her own new song, “Opportunity” by pop writer Sia, that adds to chestnuts such as “Tomorrow” and “Hard Knock Life.” The lip-synching and dancing are sloppy and the pace sometimes lugubrious, but overall the positive family vibe eclipses the misfire moments. For every dreadful performance (Bobby Cannavale), there’s a good one (Rose Byrne). For every montage miss, there’s a stirring song. It’s equal parts ashtrays and art, but in a world with few joyful enterprises, perhaps this new deal for Christmas that marches to its own drummer can also pass for an adaptation of this family favorite.
