The Use of Lucie and Desi Jr.
It seems to me that as the series moved from season to season, the kids were used less and less. I know Desi Jr left halfway through the series run, but it seemed to me the kids were just not used as best as they could. Desi Jr was a good looking guy, very charming, and he seemed to have some good episodes (Lucie always got on my nerves!) but eventually it wound up being just Lucy and Gale Gordon, like "The Lucy Show". But it didn't start with this intention, right?
