Watching, or better yet, participating in, the interaction among filmmakers and between filmmakers and audience, or, at the smallest festivals, only among audience members, adds a rewarding dimension obviously not found at a typical Friday night flick.What makes postscreen discussion different at a Jewish film festival is that a large share of comments come from people who have experienced whatever is being discussed, whatever the movie was specifically about.
