Currently , IMO, there are no good documentaries except NOVA, regarding space and physics. I agree with BoJangles
that documentaries produced today are at the 6th grade levels, and the amount of time and money spent on amazing graphics supercede any intellectual forethought or scientific data. NatGeo and History are both good at getting some of the brightest from JPL and NASA, and then ask them stupid questions like, " what is your favorite planet". Might as well ask, " what's your favorite color" On top of that, shows produced by them always mis-inform, and mis-interpret such profound things such as relativity. Matter of fact, I would go so far as to say that shows produced by these channels
are actually better suited to mis-lead the public as to inform them ( just like the liberal media). Unfortuneately we all know the kind of people who pervade Hollywood, most of them live in "lala land" and have no concept of the physical realities of the world we live. The advertising dollar is the bottom line.
Case in point. Just last week, one of those, NatGeo or History, just did a Bio/Doc on Isaac Newton. They were more interested in showing his interest in Bible Codes and trying to "DRAMATIZE" his life than to show his true genius, the birth of modern physics. All one has to do is read about his life and his accomplishments and the true drama of his life would be revealed. The fact that he was anti-establisment and walked away from the scientific community, or his early childhood and the death of his parents are drama enough.
You are much better off reading a book, taking a class in college, or going to a lecture. Find a local astronomy club,
and attend some of the meetings. Quite oft they will have marvelous speakers giving lectures on various topics. And the best thing is, they are motivated by truth..................................Al
