I always thoroughly enjoyed this bizarre claymation whenever I happened to catch it on TV. I don't think I ever saw it regularly enough to figure out exactly what the hell it was about, but the style is typically Aardman, the characters pleasingly endearing, individual and ridiculous, and the humour demented enough to appeal to the discriminating adult, whilst (from memory) not containing anything toxic to children. Haven't seen it for a while, so I'd prefer to be a bit more confident about this rating, but 3.0 feels about right from memory.
Sorry this review wasn't bigger on details. Suffice to say it's Aardman or Aardmanesuqe claymation, it's adult-oriented but suitable for kids, and it's whacked out. It's a bit edgier and a lot weirder than Wallace and Gromit, but otherwise it shouldn't present a problem for audiences of any age.
