Filmmaker/Critic David Lowry on criticism and filmmaking:

"And what marks bad criticism, from my filmmaker's perspective? It's any work by a writer who's forgotten that his or her form is just as much an art as mine. Which of course leads me back to the fact that I've been put in a somewhat tricky position by straying back and forth between those forms. But that's another post for another day in the not too distant future; for now, I'll just say that being a filmmaker has given me an invaluable perspective on criticism, but that the mutuality pretty much ends there."

Excellent post David. Read it.
