it seems pretty mixed so far, but it seems most are excited for disney's return to 2d.
Nytimes review:
"Gorgeously animated with bursts of bright purple and acid green the realistic lines of the characters explosively give way to increasingly jagged, graphic and surreal shapes this number erupts early in the story, setting false expectations for the rest of the movie and its songs and animation. Despite some ensuing comic relief, largely in the hefty form of a musical alligator, Louis (Michael-Leon Wooley), and a snaggletoothed Cajun firefly, Ray (Jim Cummings), the film sags without Dr. Facilier and his menace"
'This old-fashioned charmer holds its own beside the motion-capture elegance of Disney's A Christmas Carol, the engrossing stop-motion universes of Coraline and Fantastic Mr. Fox, the CG-enhanced genius of Up, the wonder of 3-D technology, and, indeed, the unique, hand-drawn Japanese artistry of Hayao Miyazaki's Ponyo as the year's deepest, most affecting, and most inventive movies."
