The death of the middle ground and the silence of filmmakers with something to say, here.
At least Jim Jarmusch is still making films. But his last budget for Only Lovers Left Alive (2013) was $7 million, according to IMDB. So he falls in that range of films to be made for a few million that some of the filmmakers quoted in this piece wouldn’t go back to.
The trend seems similar in publishing. Big-budget books or DIY presses. Nothing in between.
