Have just discovered this on Children's TV on BBC 1 and it's brilliant! The characters are original and charming however the stars of the show are the 'random' sheep (voiced by Mel Brookes...say no more!)
The situations featured in the stories are the things that children face all the time, which is why it appeals to all ages. The 'moral' to the tale is stated at the end, although it is the characters of the 'children' (pig, duck, bull) that makes it so charming. Although animals they are realistic.
The programme works on several layers though (especially with the sheep who offer a parrallel story)which is why its wit also appeals to adults.
This is wasted on children!
