Very enthousiastic about you getting the stories out!
What I notice is that the title is based on how the organisation of Jehovah's Witnesses presented itself in the past. It seems they try to use the Watchtower term less and less.
I'm afraid the ones who would need to see your documentary (of course JW's, but also those wanting to be JW's) will not be watching it because of the title. When I was still believing the story, I was eager to get more info on the organisation. So Wikipedia seemed to me a "safe" choice - and I was surprised to learn a lot of stuff that I didn't know as a born-in. But I would never watch a video like the ones above, out of my fear for "apostates". Isn't there a title that triggers JW's to watch this documentary?
