I'm a tiny bit confused over what this question asks, but do you mean current Parks admin or when the Parks service was fighting it out with the Forestry service over many of the parks creation (as yes, profiled a bit at least in the two episodes I've seen)?
Same here. Maybe it's the subject and its natural grandness, more live footage, tighter narrative or likely I've become more sappy over time, but it feels a baby step in the right direction over his earlier series, right up to The War, which I had more issues with.
