The only character that I would find realistic would be Stella, blanche and Stanley live a fanasty world. Blanche more that Stanley. The setting is realistic for the time period. Stella was a hard working women who wanted a better life life but lived in reality, her sister never lived in the real world that was the cause of her downfall.
