I don't know if this is true for most film festivals but at the one in my city, each film is only shown once. That means if you can't make it cause of work, or whatever reason, you don't get to see it again. And usually they are the type of movie to never go to video, so you're only option is to illegally download it or specially order and pay a little extra money, even though you would rather see it first, before deciding to pay to own it. This year I never got to see any of the films that caught my eye cause of the one time showings. Sometimes they are at very strange times like midnight, on a work night too.
