By season 6, the story lines were running a little thin. It seems that each episode only has one good story and even those are a retreads of the same idea. In season 4's Blind Date, Blanche has to grow to be with a blind man and now we see the same thing, only the man is in a wheelchair.
There are of course some great lines, especially Sophia's 'we was po!"
The story of Rose with the puppy is just a bad attempt to remind us of Empty Nest, also produced by the same team as Golden Girls. It's no surprise that Bea Arthur was ready to leave after this season. GG is a great show, but was starting to run a little dry due to shifting writers.
