I heard about the film too. Waiting for it to show up on Netflix.
I saw the movie last year at the Ojai film festival--twice. I watched it one weekend, thought a lot about it, and went back to see it again. And, now that it's out on Amazon, I may watch it a third time. It's been too long for me to comfortably share specific opinions about it, but I recall that there are many things to like. It's definitely worth seeing!
