IMO, it looks weak. Not that I want some over-the-top, "Six Screens" kind of thing but the stories in the excerpts just aren't very interesting. If you aren't a JW, there's very little appeal here. The examples given aren't really extreme enough to register a response. On this board, we tend to sympathize with those who say, "I felt like I couldn't go to college," or "I couldn't do all the sexual stuff I wanted to," or "Poor me - I had to play hoops in my dress clothes," because many of us have been there. But as for it being the subject of a film, I don't think people will care. And even if an active JW watches this, all they'll see are former JWs with complaining spirits.
Think about the kind of documentary stories that really get people talking. GASLAND, Capturing the Friedmans, Inconvenient Truth, Bowling for Columbine. These films are compelling, controversial, and incredibly entertaining. I can't say the same about this film , based on the trailer and the excerpts. In fact, this very board is full of stories much more gripping than those in this film.
But I digress. Maybe the film-maker had no intentions of making a big impact either in the JW community, or the world outside it.
At least it was shot in high quality and edited well.
