Episode one: so far it is okay at best. The problem I found was there's too much commentary by too many different people, some who have no reason or standing to comment on such an important true story.
It would have been much better to let one person narrate the areas necessary for any factual back stories, or allow the actors themselves play out much of that history and back story.
Hopefully that develops more in episode 2 and 3, we'll see.
