Based on the British series, which was based on the Oscar-winning short by Nick Park of "Wallace & Gromit," the show posits the idea that each of us has an animal within. The stop-motion animators, with Park as executive producer, take the tones and words of recorded voices and match them -- often ironically -- to funny creatures. Sometimes, the overall impact is poetic, such as tonight's image of two porcupines talking to the camera: "I'm not really scared of needles," one says, "but she probably is." Other times the effect is more overtly funny -- the image of a dog sniffing another dog's behind, while his voice exalts in the subtleties of the bouquet of a fine wine.
The not-so-great thing about "Creature Comforts" is that a little goes a long way. A half-hour of talking lobsters, caged birds, bulldogs, and fish is about 25 minutes more than we need. The sweetness of the show would be better consumed in smaller doses -- on YouTube, say, or during commercial breaks, as a way to inspire DVR viewers not to fast-forward through ads. The episodes don't have plots; they are only built on vague themes such as doctors, or secrets and lies.
And so each half-hour wanders on a bit, going nowhere special, kind of like a turtle.
