It's a very well-balanced documentary, but yes, I agree with other reviewers, SOME judgment or commentary would be nice. Because it's not really saying anything new then, it's just re-hashing what each side believes in, which isn't a mystery, really. There were a couple times also when I thought the information was misleading and borderline historically incorrect. Example- yes, Jefferson produced a version of the bible, but it was one in which he cut Jesus and God entirely out of the equation, and presented it as moral teachings. So how is that an argument towards him possibly being religious? Yes, this is a bit nit picky, but still, this is a documentary, and this was part of the background commentary and not someone's interview.
I also found some of those background explanation segments simplistic, essentially copouts. The whole "separation of church and state could mean either one". Really? It could honestly mean state can't do anything to the church but church can do anything to the state? How does that even make sense? Or the idea that we are more polarized now because citizens now have LESS of a political voice than they did during the time of the founding fathers, when only white, Christian, land-owning men were allowed to participate in the debate. Or even the idea that people are naturally going to pick the best, most "truthful" option when given the choice. Or what about some exploration of what focusing only on moral issues does to the voters, in terms of sometimes voting against their overall or economic self-interest? It just wasn't critical enough, sometimes.
