In a year of weak animated features, Frozen loosely based on "The Snow Queen" takes the lead by default. There's not much flair in the story of princess sisters Anna (voiced by Kristen Bell) and Elsa (Idina Menzel), divided by Elsa's uncontrollable ability to turn things, even Anna, to ice. But the animation is pretty, the songs are tuneful, and Josh Gad gets big laughs as Olaf, a snowman with a sun fetish. It's the holidays, people, work with it.
