The faith on action DVD is not so great for learning about the history of JWs. It's leaves out a lot of information. No mention of how they believed Christ came in 1874, how Barbour (an adventist) greatly influenced Russel, not much said about 1925, is biased in showing rutherford take the lead during the schism, no mention of 1975, other dates and previous teachings and doctrines. Rather it makes it seem like the "light gradually grew brighter" when really there were areas where it did and didn't. That DVD is the sugar coated history and barely scratches the surface. The Proclaimers book contains more information but it's really thick and not done in chronological order so it's rather confusing. plus I doubt many will take the time to actually read it from it's size. That thing is huge! But it does omit some information and minimizes certain events such as 1975. (They gave it a paragratwo or two, talking about it).
Not many Jw's will actually take the time to bother knowing their history or read anything beyond what the Society says. Basically the only get the point of view they are feeding you (only the good). If you look at outside sources, it shows a bigger picture. One way I found about what truly happened in their history is through other websites such as Wikipedia. Although people say Wikipedia isn't very reliable, you can still look up the sources to confirm that facts. Theres a lot of documentation out there especially in older publications. Jwfacts does a great job at documenting changing doctrines and how it has developed to the ones known today. Before doing that, I hardly knew anything except what was told.
Its interesting to see how they mention past discussions and books such as "millions now living will never die" and only mention parts that pertain to current doctrine (thus making it seem like that was the most important thing). In reality that booklet says much more such as the resurection of the princes in 1925 and how the old world "legally ended" in 1914 and was passing away while the new order was on it's way in. That's why it was said "millions now living will never die"
