"It was deemed important to make it as realistic as possible."
I think that quotes sums it up: so many times people are obsessed with "realism," rather than acknowledging the hyperrealism of theatre and letting things be suggested.
It reminds me of a great moment in one of my technical classes in college when my professor reminded us that theatre isn't real. It's not meant to be real. It's meant to be a suggestion of a reality that the audience accepts.
