I did enjoy this film, much more them my kids, who are under 7, which leads me to believe that it is set for older kids probably over 10s. The animation is great as anyone would expect from Dreamworks. I liked the story as well. The only complaint I had about the film was that it did get a bit repetitive towards the middle of the film.
Meet the Croods the last surviving cavemen. They survive by following the rules fear everything, and stay in the cave as much as possible. This is fine for most of the family but Eep the older daughter has a natural sense of daring and adventure, one night leaving the cave Eep meets a guy called Guy, who is scrawny but inventive and survives by his intelligence rather than his strength. Guy tells Eep the world is going to end in earth quakes and volcanic explosions, and he is moving to higher ground towards the Sun. The father/leader of the Croods (Grub) has a natural dislike for Guy for two reasons one his daughter likes him, and two his ideas are inspiring the family to forget the most important rule of fearing everything. However Grub realises he need Guy if his family is to survive.
An enjoyable family film. With great characters and good character development, al little predictable but the animation and few funny one liners make up for this all in all a good film.
