"But while we're making grand proclamations, the one thing that Lena Dunham has most definitely done for all of womankind is to emancipate them, forever and ever, from being The Friend."
Were you aware that Lena Dunham and Louis C.K. are responsible for toppling* long-standing TV tropes? Impressive work, especially considering Dunham managed it in ten episodes of one season, and C.K. has managed it in 25 or so. I might have doubted the ability of one or two programs to radically change things in such a short period of time, but that's why we have the internet: to establish timeless truths that are definitely not going to be revised at any point in the future.
*Of course, neither of them actually topples the stereotype: they merely invest them with human feeling.
