This is a rarity for me; however I have Land of the Lost Season One and that's enough. I can even say I still like the show, however one season is enough to get my Holly thang on (that sounds wrong, lol).

Do you have shows in which you have one season and you are NOT compelled to load up on all the seasons??

For me that would be Diff'rent Strokes.

For me, I would need the first season and a half of Maude. Basically, because of Esther Rolle.

Season One of The John Larroquette Show is really the only season worth having. Once they 'brightened up' the concept and brought in Alison 'Show Killer' LaPlaca, it was just HORRIBLE.

Step By Step- season 2 (Best of them all, IMO)

Married... With Children- season 7

Nurses - S1 and a half, b/c after S1, it became just really silly and slap-stickish to the point where it was an all-out slapstick fest.
