I've always felt the final season is a lot better than season 5 and 6. I think its because they made Dorothy funny again. She became far too sarcastic and was always the brunt of Jokes especially from Sophia. Which is why, i find it hilarious the way she acted, when she found out about Sophia's 30 thousand dollars. Some of the best one liners come from these late episodes.
'Ma you don't leave finger prints anymore' About Sophia's age
What about Blanche could she be more vain
'I can't dump this man, not after what i've meant to him, not after what he's done for his country.'That's her problem not the fact she's dumping a man because of his occupation (a pharmacist). Vain Vain Vain
How i love those girls
