There's considerably less drift in "Ice Age: Continental Drift," the latest in a long line of lucrative cartoons from Blue Sky Studios and their friends at Fox.

It's all sight gags and action beats, which tend to cover the shortcomings these assembly-line farces are infamous for. And at a brisk 94 minutes, it's less reliant on charm-starved chatter among its increasingly over-stuffed voice cast.

Yes, there are even MORE big names doing the talking for the various Ice Age critters - pop stars Nicki Minaj and Jennifer Lopez join Peter Dinklage, Wanda Sykes, Joy Behar, Nick Frost and Simon Pegg. But the adage that "they only add more big names to the voice cast when they're worried about the animation" doesn't apply, as this is the least chatty film of this series.

The "Ice Age" movies are known for their sloppy science, and this one has the growing extended family of mammoths (Ray Romano, Queen Latifah and now "daughter" Keke Palmer) split up by the splitting of continents.
