I can't quite get my head around this. Dunham's writing is so self-obsessed and she's completely unaware (or so she would have us think) of her class privilege. 
 Not having watched 'Girls',I don't know whether this neurotic, narcissistic tone is part of her persona, or if she really is this shallow. 
 She still has a very distinctive voice though, and the 'unfiltered', I-am-going-to-tell-you-everything-even-things-young-ladies-aren't-supposed-to-talk-about makes this fairly readable. Having said that, White Girl Problems has already done the same shtick, but better because it's fictional and funnier.
