I can certainly understand why people dumped on this show at the time with horrible sequels and ripoffs of the Bruce Willis talking baby film going around, however, I was pleasantly entertained by the handful of episodes I saw. I would really like to re watch them somehow to see if time has polished the memory or not. The voice actor saying Bob's lines was an inspired choice to my mind. Just doing another Bruce Willis thing would have made no sense. This had a very good cast of actors and the comedy was pretty sharp too.
The only pitfall for the show was the same reason it likely got made in the first place - similarity to the Look Who's Talking franchise.
