HBO's Girls is written, directed, co-executive produced, and starring a twenty-something girl--Lena Dunham. This makes me so happy I could scream. She's this one:
The girls on the show are educated college grads/students. They are intellectuals, yet they don't know when to stop talking to the booty-call guy. The kinky sex guy. Ew, yeah that guy.
WARNING: As a huge Sex and the City fan I will say that Girls is a different kind of....well set of girls. The ladies of Sex and the City are just that--ladies.

The foursome of Girls are in their early twenties and are still trying to decide what they want and who they want to be. They're awkward and dysfunctional and perfect.
