The Croods isn't particularly smart, but it has just enough wit to keep us engaged and just enough speed to keep us from feeling restless.

It captures the wonder (and more gently, the anxiety) of discovery time and time again. And the filmmakers have a hoot playing with the Croods' encounters with, as well as their misunderstandings of, all things new.

As family viewing, it's pleasant enough: primitive, yes, but in a digitally sophisticated way that's boisterous, funny and will no doubt sell a lot of toys.

Some of the action and humour might be a little crude, but this caveman comedy is guaranteed to elicit plenty of laughs from young and old.
