I'm almost 10 years late to this party, but whatevs. There was something so terribly endearing about Frankie as she oscillated between wanting to be a part of the old boys club and wanting to destroy it to form her own club with her own rules. 
 For me, the fact that she was able to recognize the parts of Matthew that made her feel undervalued, belittled or ignored and recognize that their relationship was not built on an equal plane, but still fell into it with such innocence and abandon, was the most real and relatable part of her. Smart girls don't always make smart decisions and that is as human as it gets.
