Robert Zemeckis' 3-D animated take on the Dickens classic tries hard, but its dazzling special effects distract from an array of fine performances from Jim Carrey and Gary Oldman. Ebenezer Scrooge begins the Christmas holiday with his usual miserly contempt, barking at his faithful clerk and his cheery nephew. But, when the ghosts of Christmas Past, Present and Yet to Come take him on an eye-opening journey revealing truths Old Scrooge is reluctant to face, he must open his heart to undo years of ill will before it's too late.
