Kelly2, I don't see one darn good reason as to how the message of the show would be affected by if this family was played by an all-black cast vs. an all-white cast. First of all, how does race come into play with the message of the show in the first place?
The fact that the family is on the outside a perfect, loving family, as others are mentioning, makes the message compelling. Perfect, loving families can be white, black, Hispanic, Asian, etc. So, no, I don't agree with you that it will change things. Maybe people will have a slightly different perspective of the show, but I don't think it would be one that would affect the integrity of the show or the show's true message.
'Also, do you think no African-American or Latina actresses auditioned for Next to Normal at all? The creative time chose to cast every single member of that cast of a specific race. Do you think maybe there was a reason for that?'
Talent?
