Gads that cutting back-and-forth between NO and NYC ... yes!
Pitch perfect, every detail right and correct.
Treme is a costumbrista; some describe this hispanic form as concerned with a romanticization of the culturally ephemeral. Now New Orleans is fantastic, but it is not fantasy -- not a romance. Nor is it ephemeral. New Orleans is in cyclic, wheel time, not arrow time. Once something happens, it keeps on happening. But the attention to every cultural detail of particular time and place, getting it perfect, within the story/stories being told, that is costumbrismo.
This seems even more so, as the founding hispanic element, so long overlaid by the Anglo and the French, has re-emerged since the Failure of the Levees, and Treme is showing its return ... the wheel has turned again.
Shivers, shivers, shivers.
