I saw it, and it was well done. Witnesses were also given footage, although it seemed to me that this was more as to give them a chance to give their version in a way... The brother interview in disguise, stated that the witnesses claim their organization is perfect. Well it has been said many times that the organization is made up of imperfect people, thus not perfect. However, of course by means of the way it is taught in the congregation, one is told to obey as if it was perfect...
The witnesses portrayed also gave a positive impression.
