While skimming through Manohla Dargis and A.O. Scott's "Memos to Hollywood" on nytimes.com, I noticed this bit:
To: Heads of production, Sony, Universal, Paramount, Fox, Disney
Cc: Joe Swanberg, Andrew Bujalski, Greta Gerwig, Aaron Katz and all their Facebook Friends
From: A.O.S.
You all keep trying to make Rock Hudson-Doris Day-style romantic comedies with the golden guys and gals of the moment, and the results are sexless, subtextless, bland career-girl-in-search-of-Mr.-Right retreads. Meanwhile, a bunch of hungry directors with digital cameras, time on their hands and not much money are making free-form studies about tentative hookups and long conversations among actual, overeducated, undermotivated young folks.
I'm digging Mr. Scott's vibe on this, but the phrasing "among actual, overeducated, undermotivated young folks" succinctly describes, from what I have gathered in conversation and in reading, the traits that largely turn many people off of some of the listed directors' films.
On the other hand, those same traits clearly appeal to those filmmakers' core audiences, so they must be doing something right.
