Here is a link for an article written by George D. Chryssides. I believe that he attempts to be objective or fair when writing about the religious movement known as Jehovah's Witnesses. One criticism that I have of his work, however, is that he is sloppy or careless with historical details. But maybe he is not a historian. Anyway, his article isn't that difficult to read. One more criticism might be that what is mentioned in the abstract is not fully developed by the author in his actual writing.
