Watchtower Comments is an excellent series of videos about Jehovah's Witnesses and their teachings. I periodically post the videos on this blog. They can also be viewed at the new Watchtower Comments website. Here are some videos which describe the series and discuss why both Jehovah's Witnesses and people who aren't members can benefit from watching them.
