Enjoyed this as an epilogue to the series but wish...
... the flashbacks had featured more of Walter and Jesse.
Throughout the series, they had this complex relationship that brought out the best and worst in them at various times. I enjoyed that one scene in the restaurant that reminded me that, especially in the early days, a dying Walter had a certain fatherly affection for his partner-in-crime.
It would have been nice to see a series of scenes that reminded us of this evolving relationship and ditched some of the stuff with the minor characters.
Or, maybe that might have just turned it into a BB 'greatest hits' nostalgia piece, I dunno.
