The series was terrific for all the reasons others have already stated. Very informative and interesting, rarely boring. I also loved the gorgeous photography, such as the photo of downtown Chicago at dusk, or Bigelow’s Pharmacy in Greenwich Village in the 1920s, still standing and open for business today.
One thing that was a bit irksome, though subtle enough that I don’t think I noticed it until somewhere in the second episode, were the added sound effects. A quiet “pop” over a silent clip of a man pulling a cork out of a bottle, the sound of guns being cocked upon being shown a still photo of a group of shotgun toting Feds, the sound of the wind and birds chirping during some outdoor scene that I can’t recall. Was this done in the Civil War doc, or others? Never noticed it until now.
