The series presented many cultures (Korean, Italian, biblical, Buddhist, ... ) presenting a mafia person, who somehow never forgot spoken and written Korean, and barely learned Italian, though an Italian lawyer.
He is caught in a good vs. evil war, siding with the former, though unable or unwanting to shed his old self.
In the end I wondered whether I had to go through so many killings, and why the author chose not to develop some relationships among the cast. I am not only referring to the woman protecting Vincenzo from getting shot, de facto a "I love you" declaration, which went pretty much nowhere. I am talking about developing the mom-son relationship in the Plaza, do more with the pawn shop couple, get the cook out of his goofiness by learning how to cook, ...
I also disliked the plethora of revelations about the past of the Plaza folks. Too artificial.
Liked the defenestration scene at the end of ep. 19, the re-creation of Delacroix' masterpiece "La Liberté guidant le peuple", the music overall, and the fact that the author spent time to tie together everything in the end.
