It's a great show. They aren't trying to be too critical of religion; but they do note several times where scientists and astronomers were intimidated and persecuted for discovering realities that are perceived to conflict with the Bible.
I'm a Catholic, but if you believe in the 100% historical accuracy of the Bible over proven scientific research, then you're engaging in defiant ignorance. It's not as if science/religion can't co-exist, but we must not ignore what is right there in front of us.
