I was already familiar with the original Flintstones, and with the characters of Pebbles as a cute little infant girl and Bamm-Bamm as the little infant boy who was strong and clever for his age, though neither learned how to speak yet. And this would of course be the "second generation" (or rather half a one) version, how would they grow up?
Not unsurprisingly it was essentially a teen comedy akin to the Archie comic. But the two characters could have at least retained some characteristics of their old selves. Worst of all was Bamm-Bamm, no longer the strong and clever infant but a rather dense teenager, not even strong like he used to be. No surprise this spinoff did not last.
