Basically A Rewrite of "The Glass Menagerie" (Spoilers Possible)
Wouldn't you say so?
You have the strong Southern belle mother trying to handle her lot in life, a crippled sister (only this time, emotionally and very suicidal) and the brother who distances himself from them yet has emotional scars of his own.
Throw in a female psychiatrist and add a bit of comedy plus a love story, and there you are.
What once were vices are now habits.
