He's a popular historian (though I've never heard of him) - but I wonder how many of the 27,000 viewers avidly watched all 12 hours?
I'm personally a bit down on history right now. Here's the problem: everything written in the first 50 years after, say, a war is partisan and incomplete. After 50 years, it just becomes too difficult to find out what actually happened.
In looking at the past, best to focus on technological progress:
1. that's the REAL story
2. everything else is, at best, a "story based on fact"
