This animated film about the 'first family' finding its way across a pre-historic landscape, led by a slightly less pre-historic man as guide, is full of good visual one-liners, and plays very neatly on the dynamics of the family. As is becoming normal these days, it works on two levels: lots of visual slapstick for the children, and knowing phrases and looks catering for some adult humour too. I enjoyed this film, though it's no classic. My only negative comment would be that three of 'the family' are not as well developed as the others. If you see the film, you'll find out what I mean.
   My favorite line? "Release the baby!"
