That's what's wrong with indie cinema, documentaries and small movie projects. Another film I'm interested in, I'm ready to purchase and watch, yet I can't since it's not available anywhere, except for some screenings in a handful of places worldwide. So it ends up as an easy to miss entry on my ever growing to do list hoping to be re-discovered and some day.
I understand (though not agree with) the argument for theatrical windows for big, mainstream blockbuster movies. However what is the point of artificially and severly limiting the availability of niche releases like these? Your target audience is already tiny - unnecessary barriers certainly don't help.
