DoC: Sad to say, I don't see a big audience for this. The public really doesn't care about JWs because they are such a minority of the population, a nuisance (and mostly weird).
JW's, of course, will be told to boycott it.Only family members who have been affected by a JW refusing transfusion will have any remote interest.
The only reason that "the public" shows little interest is simply because they are ignorant of the the full implications of the WT's blood ban.
I used to think the same as you, Doc, until I started talking to non-JWs about the blood ban and it has been surprising how many people are totally unaware of how much this issue has affected those affiliated with the JWs. The "public" that I have spoken to about the blood issue have been horrified when they learn how many JWs die each year from refusing blood.
They have simply shown no interest because they know nothing about it. This film will change that.
