I generally agree that the babyfication of anything usually ruins it, but Muppet Babies was a quality show. I agree that most of this has to do with age. I probably watched more Muppet Babies than Muppets, but I am 29, so that is understandable. Today, if both shows came out, I imagine I would like the Muppets more than Babies, but back then it was totally the opposite, so that's how I voted.
I guess you can always go with the argument that without the Muppets, there would be no Babies...I am a little in disbelief that this poll is even somewhat competitive, but glad.
