Sounds really stupid. I don't even think the commercials were all that clever either. I don't see how they could make anything good lasting a half hour out of it. I mean the caveman on the commercials isn't even much of a caveman other than having the facial features and hair. He seem pretty modern to me so it wouldn't be much of a "fish out of water" story. Besides, that's been done to death anyway what with Alf, Perfect Strangers, Mork and Mindy, etc. etc.
