There was an interesting documentary on the Mormons yesterday. You could substitute JW for Mormon for most of it (except teachings) especially concerning obedience to the higher ups, not questioning the organization, etc. They disfellowship and excommunicate (excommunication being a worse fate) and if anyone questions the church they are considered an apostate.
I checked to see if it was going to air again in the near future but so far no plans. You can however go to www.pbs.org and watch it.
