DVD Documentary: covers all the U.S. presidents
 

I borrowed it from the Sumter County Library System. It covers all the presidents from the first to the current president. I haven't finished yet, I'm a little more than half way through.

It's very interesting and seems to be even handed in the way it tells about the successes and failures of each president. But how would I know for sure? Maybe when I get to the more recent ones? But I doubt it because I am biased and therefore my perception would be too.

Can we ever totally rely on historians to report history in an unbiased way?
