@Danzig! yes. this. I just watched the first episode, and Lena Dunham's character was so grating to me I had difficulty watching the whole thing. Even if there IS supposed to be satire, I feel like it's being done pretty hamhandedly (is that a word?) and I basically just cringed for an entire hour, with brief moments of missing living in the city (like when the guy yells at her at the end).
And yeah, as everyone has said...how someone can live in NYC and only have white people in their lives seems a bit strange. (or at least unlikely).
