I hope you enjoyed Ticket to Heaven,” I've been recommending it for years.
When I first saw it, my reaction -- I was still "dubbish" -- was, "Wait, that's like us."
Of course the JWs and the cult depicted in "Ticket" are not identical in all aspects, but that is what makes the movie so valuable. It creates "micro-dissonance," and cognitive cracks NEVER get smaller.
On thing you have to allow for, SAHS, is the great amount of investment you folks have with the WTB&TS. Its as though they've spent their lives waiting for the Nigerian Prince to finally come through on his promises... they are likely to prefer continuing to wait rather than admit that they were hoodwinked.
