Crrrreeeeeeeak! That sound you hear is the door to the ballyhooed Now We Know vault, once again being opened to fetch your now-unlocked, once-paywalled episode for the week. This time it's Family Dog, the Steven Spielberg-backed, Brad Bird-created cartoon which aspired to be CBS' answer to The Simpsons. This was decidedly not successful, although at just ten episodes long, is it theoretically possible that a higher percentage of the entire run of Family Dog is better than the entire now-moribund 37 SEASONS OF SIMPSONS????? Probably not, but this much is true, at least: we never had to hear Martin Mull struggle to voice the dad from Family Dog into his 70's.
