An excellent radio show interview with Andrew Holden discussing his new book 'Jehovah's Witnesses' is available as the transcript at http://www.abc.net.au/rn/relig/spirit/stories/s562491.htm It's not at all negative, just quite an accurate account of what they're about basically from their side. For example he discusses their rationalist approach to religion and so on. They also interview a City Overseer, (presumably) a Pioneer and a counsellor for ex-JW.
