I know it's a musical and that may turn you off, but there are parts of it that deals with how the founding fathers wrestled with the problem of slavery in writing the Declaration of Independence. Knowing in hindsight what would happen 80 some years down the road, how the compromises they made at the time to pass the Declaration would come back to bite the country in the ass in the mid 1800's. I watched it once trying to ignore the musical aspect and trying to absorb the history around it and the signers.
