Synecdoche, NY

I was watching "The Colbert Report" tonight and his guest was someone who worked on the movie "Synecdoche, NY". It is a story of cities living within cities living within people's minds. Since synecdoche basically means referring to something by referring to a part of a whole of the subject, the models of New York City in the actual NYC are synecdoches. Towards the end of the interview, Colbert asked the guest "what is the correct way to understand and watch this movie?"; to this the guest only said "Whatever you want, the viewer can only be right." This directly connects with Reader Response criticism in the fact that the reader's interpretation of the text is the text. I'm definitely seeing this one in theaters...if i can.
