3.5 stars Starring: Forest Whitaker, Keegan-Michael Key, Madalen Mills, Ricky Martin, Anika Noni Rose, Phylicia Rashad, Hugh Bonneville, Justin Cornwell and Lisa Davina Phillip Rating: PG, for no particular reason Opulent musical fantasy is laden with seasonal charm By Derrick Bang This is an impressive slice of holiday razzle-dazzle. The tag line for writer/director David E. Talbert’s opulent fantasy promises that viewers will “discover a world of wishes and wonder,” and that’s an understatement. This often breathtaking blend of “Alice in Wonderland,” “Babes in Toyland” and “Hugo” also seems to be gunning for the seasonal crown long worn by “The Wizard of Oz.”
