Fast-paced but not frantic, goofily good-natured and attractively designed for widescreen 3D, this splashy new effort from Tom McGrath, who made the Madagascar hits, happily avoids the crassness and relentless showbiz referencing that have marred some past DreamWorks Animation entries. With its nifty concept and high-octane cast, this Paramount release looks to rake in strong returns with general audiences through year's end, and it would be a shock not to see a sequel down the line.
