I recently attended the seventh annual Art House Convergence, a four-day gathering of more than 400 people from all over the world who are devoted to making, distributing and showing quality films. The event, held under the auspices of Sundance, is devoted to the idea that cinema should be promoted and cherished as one of the world’s most important art forms. What’s interesting, though, is that where some people see real value in a particular film, others see vapid entertainment. Which may explain why filmmaker Jeremy Saulnier felt the need to apologize for the fact that his movie, Blue Ruin, which was screened there is a genre film. And that’s the art house paradox.
