The stories move along quickly, which is a huge relief. So many documentary type shows drag and repeat and drag and repeat.
The negative to this show is that there is more film used on the fake than the real. We tuned in to see the actual places and they didn't show them much. Instead we get the reenactors in barely lit rooms. A mocking drinking game could be made out of the number of times you see an actor look "meaningfully" at the camera. We'd much rather see more and longer shots of film/photos/paintings of the actual buildings and environs and people and things that the stories are about. And there's no need to show the narrators more than once.
We enjoy listening to the stories though and hope they continue.
