Fresh off my DVR, I just watched the History Channel's "Opus Dei: Revealed" documentary and to my shock and disbelief, it was actually a pretty well balanced presentation. (for the History Channel). I don't know what they put in the water at the History Channel to do that but whatever it is they should keep it coming.
Oh sure they had negative stuff, but the Opus Dei people and detractors both got their say. Its worth watching in my opinion, since they don't paint a horrible picture of Opus Dei with broad strokes.
