I've come around to Rosa more and more over time.  At first I was a bit jaded by the larger energy of the Chibnall era and the way this feels like it is told from Graham's perspective more than anyone.  The time travelling Nazi is also extremely weird for a choice and it feels like this story is just begging to be a pure historical instead.

Yet Rosa remains a pretty powerful piece of fiction.  Malorie Blackman and Chris Chibnall do a pretty good job at telling a family-oriented story about Jim Crow-era America without shying away from the horrors of that time.  I think its a powerful and important thing for the show to explore and definitely appreciate this as a rare moment of greatness that was lacking all too often in the Chibnall era.
